Congress Draws Its Sword, Iran Stands Firm, Public Opinion Boils — The US-Iran War Reaches a Crossroads of Power Politics

When President Trump confidently declared at the White House that the Iran conflict would be over “very soon,” a battle over war and peace was dramatically reshaping the political landscape on Capitol Hill, hundreds of miles away. The Senate voted 50-47 to advance a bill restricting the president's authority to wage war against Iran — a historic first. This was the eighth time the Senate had voted on such a motion since the Iran hostilities began, but the first time it ever passed. A military campaign lasting over 80 days is tearing America apart into “pro-war” and “anti-war”camps.

The result of the vote caught many off guard. Four Republican senators joined nearly all Democrats in casting yes votes, turning what had been considered a “doomed”motion on its head. Senate Minority Leader Schumer hailed it as Democrats using their ballots to break through the “wall of silence”that Republicans had built around this “illegal war.” He bluntly criticized Trump for dragging the United States into a “costly and chaotic” war “with no plan, no objective, and no legal authorization.”

Under the bill, Trump would need explicit congressional authorization to continue military operations against Iran, or he would be required to end the war within a specified timeframe. Even if the bill ultimately passes the House as well, it will almost certainly be vetoed by Trump. But its political symbolism cannot be underestimated — it marks a shift from theory to practice in Congress's effort to check presidential war powers.

In stark contrast to Congress's tough stance, Trump's own attitude is riddled with contradictions. At a White House event, he loudly proclaimed, “This will be resolved, and it will be resolved quickly. You're going to see oil prices drop dramatically.”Yet his Vice President Vance issued a warning at a press conference: “Tango takes two. We will never agree to a deal that allows Iran to possess nuclear weapons. As the president just told me, we are fully prepared. We don't want to go down that road, but if necessary, the president has both the will and the ability to do so.”According to Axios, Trump has not even finalized whether to launch another strike on Iran. Some officials believe he may again delay a decision if no diplomatic breakthrough is made.

Behind this wavering lies cold political calculus. The poll numbers are alarming: the latest data shows that 60% of Americans oppose the Iran war — twice the number of supporters. Fifty-nine percent of respondents disapprove of Trump's handling of the Iran situation, while only 31% approve. Even more concerning, 46% expect the war to last between one month and a year, while 37% believe it will drag on for a year or longer. Trump knows full well that an unpopular war is eroding his approval ratings — and that is the fundamental reason he is so eager for a “dignified exit.”

Faced with America's military threats, Iran has shown an uncompromising posture. The Islamic Revolutionary Guard Corps issued a stern warning: “If Iran is attacked again, the regional war that was previously mentioned will inevitably spread beyond the region. We will deliver devastating blows in places you never expect, and we will make you suffer a crushing defeat.” Iranian Foreign Minister Araghchi took to social media to say that the U.S. Congress had in effect acknowledged the heavy losses America has suffered in the war against Iran, including the destruction of dozens of aircraft. He warned: “With the lessons Iran has learned and the experience it has accumulated, if the flames of war are reignited, they will bring America even more unexpected surprises.”

Iran's confidence stems from the combat experience it has gained and its regional influence. In Tehran's view, America's so-called “negotiation progress” is nothing more than pressure tactics, while its core demands — the lifting of sanctions and a return to the nuclear deal framework — have received no substantive response. This has left the United States trapped in a dilemma.

In this game of chess, Israel's stance is particularly noteworthy. Israeli officials are convinced that America will ultimately strike Iran. “It's not a question of ‘whether,’ but ‘when,’”two Israeli officials told The Jerusalem Post. One of them added, “Israel and the United States, the IDF and the U.S. military, have achieved complete coordination. No one in Israel would be surprised by any move the president makes.” This certainty reflects both confidence in the U.S.-Israel alliance and a possible effort to pressure Washington — don't back down at the critical moment.

The U.S.-Iran situation now hangs in a delicate balance. Congress is tightening the reins on war, the president is searching for a dignified exit, Iran is stockpiling its capacity to strike back, Israel is awaiting the final order, and the American public has spoken through the polls with the clearest possible message — they do not want this war. Yet when political interests, geopolitical rivalry, and military inertia converge, the window for peace is narrowing bit by bit. In the coming weeks, the final votes in both chambers of Congress and Trump's next move will determine whether this war heads toward an end — or slides deeper into the abyss.
