When Israel launched a surprise military strike on Iran last week, it did more than risk igniting a catastrophic regional war. It also exposed long-simmering tensions in Washington—between entrenched bipartisan, pro-Israel hawks and a growing current of lawmakers (and voters) unwilling to be dragged into another Middle East disaster.

“This is not our war,” declared Rep. Thomas Massie (R-KY), one of the House’s most consistent antiwar voices. “Israel doesn’t need U.S. taxpayers’ money for defense if it already has enough to start offensive wars. I vote not to fund this war of aggression.” On social media, he polled followers on whether the U.S. should give Israel weapons to attack Iran. After 126,000 votes (and 2.5 million views), the answer was unequivocal: 85% said no.

For decades, questioning U.S. support for Israel has been a third rail in Congress. But Israel’s unprovoked attack on Iran—coming just as the sixth round of sensitive U.S.-Iran nuclear talks were set to take place in Oman—sparked rare and unusually direct criticism from across the political spectrum. Progressive members, already furious over Israel’s war on Gaza, were quick to condemn the new offensive. But they weren’t alone.

Rep. Pramila Jayapal (D-WA) called Israel’s strike “reckless” and “escalatory,” and warned that Prime Minister Netanyahu is trying to drag the U.S. into a broader war. Rep. Chuy García (D-IL) called Israel’s actions “diplomatic sabotage” and said, “the U.S. must stop supplying offensive weapons to Israel, which also continue to be used against Gaza, & urgently recommit to negotiations.”

Rep. Summer Lee (D-PA) was even more blunt. “The war criminal Netanyahu wants to ignite an endless regional war & drag the U.S. into it. Any politician who tries to help him betrays us all.”

Netanyahu’s strikes on Iran are acts of diplomatic sabotage that risk escalation, endangering civilians in both countries & across the region.

The US must stop supplying offensive weapons to Israel, which also continue to be used against Gaza, & urgently recommit to…

More striking, however, were the critiques from moderate Democrats and some Republicans.

Sen. Tim Kaine (D-VA), a longtime advocate for requiring congressional approval before the U.S. gets involved in new wars, blasted Israel for jeopardizing planned U.S.-Iran diplomacy. “The American people have no interest in another forever war,” he wrote. Sen. Jack Reed (D-RI), Ranking Member of the Senate Armed Services Committee, warned that strikes “threaten not only the lives of innocent civilians but the stability of the entire Middle East and the safety of American citizens and forces.”

Some pro-Israel Democrats are feeling comfortable speaking out on this conflict because it fits their anti-Trump critique. Sen. Maria Cantwell (D-WA) said:

We are at this crisis today because President Trump foolishly walked away from President Obama’s Iran nuclear agreement under which Iran had agreed to dismantle much of its nuclear program and to open its facilities to international inspections, putting more eyes on the ground. The United States should now lead the international community towards a diplomatic solution to avoid a wider war.”

Adding to this diverse chorus of opposition are some Republicans from the party’s non-interventionist wing. Sen. Rand Paul (R-KY) declared, “War with Iran is not in America’s interest. It would destabilize the region, cost countless lives, and drain our resources for generations.” Rep. Warren Davidson (R-OH) lamented that “some members of Congress and U.S. Senators seem giddy about the prospects of a bigger war.”

War with Iran is not in America’s interest. It would destabilize the region, cost countless lives, and drain our resources for generations.

We should pursue diplomacy, not destruction. Engaging in dialogue with adversaries is not weakness; it’s the strength of a confident nation…

And in a rare show of agreement with progressive critics, Rep. Marjorie Taylor Greene (R-GA) blasted the hawks in both parties. “We’ve been told for the past 20 years that Iran is on the verge of developing a nuclear bomb any day now. The same story. Everyone I know is tired of U.S. intervention and regime change in foreign countries. Everyone I know wants us to fix our own problems here at home, not bomb other countries.”

Of course, many in Congress rushed to support Israel. Senate Republican leader John Thune said, “Israel has determined that it must take decisive action to defend the Israeli people.” Democratic Sen. John Fetterman (D-PA) voiced full support for the strike and urged the U.S. to provide Israel “whatever is necessary—military, intelligence, weaponry.”

Our commitment to Israel must be absolute and I fully support this attack.

Keep wiping out Iranian leadership and the nuclear personnel.

We must provide whatever is necessary—military, intelligence, weaponry—to fully back Israel in striking Iran. https://t.co/3lm1YD6dVr

The most crass was Senator Lindsey Graham, who posted:

Game on. Pray for Israel.”

But these crude pro-war responses, once guaranteed to go unchallenged, are now being met with resistance–and not just from activists. With public opinion shifting sharply–especially among younger voters, progressives, and “America First-ers” – the political calculus on unconditional support for Israel is changing. In the wake of Israel’s disastrous war in Gaza and its widening regional provocations, members of Congress are being forced to choose: follow the AIPAC money and the old playbook–or listen to their constituents.

If the American people continue to raise their voices, the tide in Washington could turn away from support for a war with Iran that could plunge the region into deeper chaos while offering no relief for the suffering people of Gaza. We could finally see an end to decades of disastrous unconditional support for Israel and knee-jerk support for catastrophic wars.
