The Pentagon’s announcement that U.S. forces conducted a strike killing one of Iran’s top generals sparked a firestorm on Capitol Hill, with many members of Congress praising the move and others warning of unintended consequences.

The avalanche of reactions came after the Defense Department said in a statement it had conducted an airstrike on Baghdad International Airport to kill Maj. Gen. Qassem Soleimani, the head of Iran’s elite Quds Force.

Soleimani helped direct Tehran’s proxies across the region and is believed to be responsible for several attacks on U.S. troops in Iraq conducted by Iranian-backed militias.

The Pentagon said Soleimani was “actively developing plans to attack American diplomats and service members in Iraq and throughout the region” and was “responsible for the deaths of hundreds of American and coalition service members and the wounding of thousands more.”

“Qassem Soleimani masterminded Iran’s reign of terror for decades, including the deaths of hundreds of Americans.

Some congressional Republicans who, at times, criticize Trump also backed the attack, saying the assassination was the right decision.

“This is very simple: General Soleimani is dead because he was an evil bastard who murdered Americans. The President made the brave and right call, and Americans should be proud of our servicemembers who got the job done,” Sen.

The strike against Soleimani, which also killed Abu Mahdi al-Muhandis, the deputy commander of an Iran-backed militia in Iraq, could lead to further escalations in an already deteriorating situation in the Middle East.

The U.S. military struck an Iranian-backed militia group in Iraq on Sunday after a rocket attack Friday killed a U.S. contractor and wounded four U.S. troops. The Trump administration blamed the attack on this group.

The militia and its supporters responded by storming the U.S. Embassy in Baghdad on Tuesday, prompting the U.S. military to deploy 100 Marines as reinforcements at the embassy and 750 more troops to the region.

Some Democrats expressed concerns that the killing of Tehran’s top general could lead to a fiercer beating of the war drums in Iran and could put American interests in the Middle East at risk.

“I urge members of Congress on both sides of the aisle to show courage on this issue, and I urge the Trump administration to change course and pursue diplomacy before we are entangled in yet another war in the Middle East with no end in sight,” he added in a statement.

“[Qassem Soleimani] was an enemy of the United States with American blood on his hands. But the question we’ve grappled with for years in Iraq was how to kill more terrorists than we create. That’s an open question tonight as we await Iran’s reaction to Donald Trump’s escalation, which could ignite a regional war, with still no strategy from the Administration,” said Rep.

Some Democrats also argued that Trump did not have the authority to order the strike without congressional approval.

“Soleimani was an enemy of the United States. That’s not a question,” Sen. Chris Murphy Christopher (Chris) Scott MurphyGOP chairman to release interim report on Biden probe 'in about a week' This week: House returns for pre-election sprint Battle over timing complicates Democratic shutdown strategy MORE (D-Conn.) tweeted. “The question is this — as reports suggest, did America just assassinate, without any congressional authorization, the second most powerful person in Iran, knowingly setting off a potential massive regional war?”

Republicans pushed back on the criticism, saying Trump had an obligation to respond to past attacks and prevent future assaults on American assets in the region.

“Gen. Soleimani has killed hundreds and hundreds of Americans, and was actively plotting more. This commander-in-chief — any C-in-C. — has an obligation to defend America by killing this bastard,” Sasse said in response to Murphy’s statement.

While the debate raged in Washington over the effectiveness and legality on the killing of Soleimani, the Pentagon left the door open to future actions to deter Iranian attacks.

“This strike was aimed at deterring future Iranian attack plans,” the Defense Department said. “The United States will continue to take all necessary action to protect our people and our interests wherever they are around the world.”
