Iran Launches Missile Wave at Israel as US Republicans Block Measure to Halt Air Campaign

Introduction

Iran launched a fresh wave of missiles at Israel on Wednesday, March 5, 2026, as the conflict entered its sixth day. Meanwhile, in Washington, Senate Republicans blocked a Democratic-led measure to halt President Donald Trump’s air campaign against Iran, highlighting the deep political divisions over the war and raising constitutional questions about presidential war powers.

The twin developments—military escalation abroad and political gridlock at home—underscore the challenges facing the United States as it navigates its most significant Middle East military operation since the Iraq War.

Iran’s Latest Missile Wave

Scale of the Attack

Iran fired a new wave of missiles at Israeli territory on Wednesday, continuing its retaliation for the US-Israel operation that killed Supreme Leader Ayatollah Ali Khamenei. The attack featured:

Multiple missile types: Including ballistic missiles and possibly cruise missiles
Broad targeting: Military installations, infrastructure, and urban areas
Air defense engagement: Israel’s Iron Dome and other systems intercepting incoming projectiles
Civilian impact: Sirens sounding across Israeli cities, residents seeking shelter

The attack represents Iran’s continued commitment to retaliation despite the damage inflicted on Iranian military and nuclear facilities by US-Israel strikes.

Israeli Response

Israel has maintained its military pressure on Iranian-backed forces:

Lebanon operations: Continuing strikes on Hezbollah positions
Air defense: Intercepting incoming Iranian missiles
Counter-strikes: Targeting Iranian military assets in Syria and elsewhere
Civil defense: Protecting population centers from missile attacks

The missile exchange highlights the vulnerability of both nations to long-range attack and the limitations of even the most sophisticated air defense systems.

US Senate War Powers Vote

The Measure

Senate Democrats, led by Senator Tim Kaine of Virginia, introduced a resolution under the War Powers Resolution of 1973 to:

Terminate US military operations against Iran
Require congressional authorization for continued engagement
Limit operations to defensive purposes only
Restore constitutional war powers to Congress

The resolution argued that President Trump had exceeded his constitutional authority by launching military operations against Iran without congressional approval.

Republican Blockade

Senate Republicans voted to block the measure from advancing, arguing:

Presidential authority: The commander-in-chief has broad powers to conduct military operations
Defensive nature: The operation protects US national security
Ongoing conflict: Halting operations mid-conflict would endanger American forces
Democratic timing: The vote was politically motivated

The vote fell largely along party lines, with most Republicans supporting the president and most Democrats supporting the war powers resolution.

The Vote Count

The measure failed to achieve the 60 votes needed to overcome a filibuster, with Republicans maintaining a united front in support of the president’s authority to conduct the Iran operation without explicit congressional authorization.

Constitutional Clash Over War Powers

The Constitution’s War Powers

The US Constitution divides war powers between Congress and the president:

Congress: Has the power to declare war (Article I, Section 8)
President: Serves as commander-in-chief of the armed forces (Article II, Section 2)
War Powers Resolution (1973): Requires congressional authorization within 60 days of military operations

The current conflict highlights the tension between these constitutional provisions and the realities of modern military operations.

Democratic Arguments

Democrats and constitutional scholars supporting the resolution argued:

Unconstitutional war: Trump launched military operations without congressional approval
Iraq War parallels: Similar justifications (WMD threats) proved false in 2003
Congressional prerogative: The Constitution grants war-declaring power to Congress
Checks and balances: Executive power must be constrained to prevent tyranny

Senator Tim Kaine, who led the resolution, stated: “The Constitution is clear—Congress has the power to declare war, not the president. This illegal, unauthorized war must end.”

Republican Counter-Arguments

Republicans defending the president’s authority argued:

Commander-in-chief powers: The president has inherent authority to conduct military operations
National security: Iran posed an imminent threat that required immediate action
Congressional notification: The administration briefed congressional leaders
Authorization flexibility: The 2001 and 2002 AUMFs may provide sufficient authorization

The Republican position reflects a broad interpretation of presidential war powers that has been consistent across both Democratic and Republican administrations for decades.

Historical Context

War Powers Precedents

The current debate echoes earlier conflicts:

Korean War (1950-1953): Fought without a congressional declaration
Vietnam War (1955-1975): Congress passed the War Powers Resolution in response
Kosovo (1999): NATO bombing campaign without congressional approval
Libya (2011): Obama administration conducted operations without explicit authorization
Syria (2014-present): Multiple administrations have conducted strikes without new authorization

Each conflict has tested the boundaries of presidential war powers, but Congress has rarely successfully constrained ongoing military operations.

The 2001 and 2002 AUMFs

The Bush-era Authorizations for Use of Military Force (AUMF) against al-Qaeda and Iraq have been used to justify operations across the Middle East for over two decades. The Iran operation represents an expansion of these authorizations to target a state that was not their original focus.

Political Implications

Domestic Politics

The war powers vote has significant domestic political implications:

For Democrats:

Opportunity to challenge Trump on constitutional grounds
Appeal to anti-war voters and constitutional conservatives
Risk of appearing weak on national security

For Republicans:

Support for the president strengthens party unity
Risk of expanding executive power for future Democratic presidents
Challenge of explaining constitutional position to voters

For the President:

Congressional support validates military operation
Victory in war powers vote strengthens executive authority
Ongoing conflict creates political risks if operations fail

Electoral Considerations

The Iran conflict could influence the 2026 midterm elections:

Republican advantage: Strong national security stance may motivate base voters
Democratic opportunity: War weariness could mobilize anti-war voters
Swing voters: May decide elections in competitive districts
Veterans and military families: Key constituency affected by prolonged conflict

International Reactions

Allied Governments

US allies have had mixed reactions:

Israel: Strongly supports US operations against Iran
European Union: Divided between supporting US security and avoiding escalation
Gulf states: Condemn Iranian attacks while wary of regional expansion
NATO: Balancing alliance solidarity with concerns about mission creep

Adversarial Governments

US adversaries have condemned the operation:

Russia: Has condemned US aggression and warned of consequences
China: Announced mediation effort with special envoy to Middle East
Iran: Continues retaliation and rejects diplomatic off-ramps
North Korea: Has criticized US military intervention

International Organizations

Global institutions have expressed concern:

United Nations: Secretary-General has called for de-escalation
IAEA: Emergency meetings on nuclear facility risks
Human Rights Council: Monitoring civilian casualties

Regional Military Situation

Current State of Conflict

As of March 5, 2026, the conflict involves:

US operations: Continued strikes on Iranian military and nuclear facilities
Israeli operations: Defense against Iranian missiles; strikes on Hezbollah
Iranian retaliation: Missile and drone attacks on Israel, US bases, and Gulf states
Regional spillover: Hezbollah in Lebanon, militias in Iraq and Syria

The conflict has killed hundreds of people, displaced thousands, and disrupted global oil markets.

Escalation Risks

Several factors could expand the conflict:

Hezbollah escalation: Full-scale war between Israel and Lebanon
Gulf state involvement: Direct confrontation between Iran and Saudi Arabia/UAE
Cyber attacks: Escalation to information warfare and infrastructure attacks
Terrorist attacks: Iranian proxies targeting Western interests globally

Future Scenarios

Short-term Possibilities

In the coming days and weeks:

Scenario 1: Continued Escalation

Iran maintains missile attacks
US increases air campaign intensity
Regional conflict expands
Congressional opposition grows

Scenario 2: Diplomatic Off-ramp

China or other mediators facilitate dialogue
Ceasefire negotiations begin
Military operations pause
Long-term negotiations commence

Scenario 3: Military Resolution

US-Israel operations achieve objectives
Iranian retaliation capability degraded
New Iranian leadership emerges
Conflict winds down

Long-term Implications

Regardless of how the current conflict ends:

Presidential war powers: Precedent set by this operation will influence future conflicts
Congressional role: War powers debate will continue in Congress and courts
US-Iran relations: Relationship fundamentally transformed for a generation
Regional order: Middle East security architecture permanently altered

Conclusion

The Iranian missile wave and the Republican blockade of the war powers resolution represent two fronts in a single crisis: the military conflict abroad and the constitutional conflict at home.

On the military front, Iran’s continued missile attacks demonstrate that the US-Israel operation has not eliminated Iranian retaliatory capability. The conflict shows no signs of de-escalation, with both sides committed to continued military action.

On the constitutional front, the Senate vote highlights the ongoing tension between presidential authority and congressional war powers. Republicans’ decision to block the resolution preserves President Trump’s ability to conduct the Iran operation without explicit congressional authorization—but also expands executive power for future presidents of both parties.

The parallel developments illustrate a fundamental challenge of American democracy: when military operations begin without congressional authorization, they create facts on the ground that make congressional constraints politically and practically difficult. The Constitution’s war powers provisions were designed to prevent precisely this scenario, but decades of precedent have effectively nullified Congress’s constitutional role.

For now, the missiles continue to fly and the constitutional debate continues without resolution. The Iran conflict will eventually end—but the war powers question it has raised will persist long after the shooting stops.
