Progressive-leaning lawmakers of the Democratic Party immediately voiced their intense outrage following the United States-Israel operations in Iran on 28 February 2026.
Representatives Alexandria Ocasio-Cortez and Ro Khanna labeled the strikes as unconstitutional. They argued that bypassing the U.S. Congress constitutes an impeachable offense while risking a catastrophic generational war in the Middle East.
The establishment leadership within the party adopted a much more cautious tone.
Senate Minority Leader Chuck Schumer criticized the administration for failing to provide sufficient briefings. He emphasized that the White House currently does not have a coherent and sustainable strategic endgame.
A third faction of moderate Democrats signaled their support for the surprise military operation in Iran that killed Iranian Supreme Leader Ali Khamenei.
Senator John Fetterman and Representative Josh Gottheimer viewed the strikes as necessary. They argued that stopping the nuclear ambitions of the Islamic Republic of Iran remains a vital priority not only for U.S. national security but also for global security interests.
Furthermore, Representative Greg Landsman defended the military action in Iran and said that the operation is targeting military infrastructure.
The timing of the strikes caused significant confusion among lawmakers away for the weekend.
Several Democrats are now seeking to curb the ability of the U.S President to engage in military actions. Senator Tim Kaine is leading the charge for a Senate vote. Some isolationist Republicans, including Representative Thomas Massie, joined the Democratic push.
Inconsistencies between the Pentagon and the White House complicated the Democratic response further. Secretary of State Marco Rubio hinted that the strikes were limited. But President Donald Trump later released a video encouraging the Iranian people to take over.
Nevertheless, oppositions within the party aside, the majority of Democratic lawmakers remain opposed to the recent military strikes.
The Republican Party also struggles with the same anti-interventionist base and traditional pro-security establishment divide. Specifically, while most Republican lawmakers support Trump, a handful believe that the U.S. should focus on domestic affairs instead.
