Israel Signals Solo Action on Iran as US-Iran War Support Crumbles

The ongoing US-Iran conflict that began February 28, 2026 has generated significant casualties and regional displacement, though specific numbers are not detailed in this report.
Israel would have to find it elsewhere—in its own military capacity
Ben-Gvir signals Israel may act unilaterally as American support for the Iran conflict erodes.

As American resolve in the Middle East visibly wanes — measured in polling numbers, Senate votes, and a widening gap between official optimism and public doubt — Israel's National Security Minister has signaled that his country will not be bound by Washington's hesitation. Four months into a conflict that began on February 28, the question of who bears responsibility for confronting Iran's nuclear ambitions is no longer a matter of alliance consensus, but of diverging urgencies. History has seen this before: the moment when a junior partner decides the senior one has grown too weary to act, and chooses to move alone.

  • Israel's National Security Minister declared his country prepared to strike Iran independently, framing American diplomacy as dangerously naive in the face of a nuclear threat it considers existential.
  • Only 23% of Americans believe the ongoing US-Iran conflict has been worth its cost, with 35% saying the United States now stands weaker than before the fighting began — a polling collapse that has reached Capitol Hill.
  • The Senate passed a war powers resolution 50-48 directing President Trump to halt military operations against Iran, a bipartisan rebuke that would have been unthinkable at the conflict's outset.
  • Trump countered with record oil flow figures through the Hormuz Strait, framing the war as a strategic success — but the distance between his narrative and public perception has grown too wide to paper over.
  • With ceasefire prospects doubted by a majority of those surveyed and congressional appetite for open-ended commitment evaporating, the alliance architecture sustaining the campaign appears to be quietly coming apart.

Israel's National Security Minister Itamar Ben-Gvir declared on Tuesday that his country would not wait for American backing to confront Iran's nuclear program — the responsibility, he said, belonged to Israel alone. His words landed at a moment when American commitment to the conflict, now four months old, was fracturing on multiple fronts.

President Trump offered a different reading of events. He announced that 19 million barrels of oil had moved through the Hormuz Strait in a single day — an all-time record, he claimed — and posted the figure on Truth Social as proof that his strategy was working. Oil prices were falling. The world was safer. The conflict was succeeding.

The polling disagreed. A Reuters/Ipsos survey found only 23 percent of Americans believed the war had been worth its cost, with just half of Republicans sharing that view. Thirty-five percent said the United States was now weaker relative to Iran than before the fighting began. The gap between the president's confidence and the public's judgment had become difficult to ignore.

In the Senate, that gap became a vote. Lawmakers passed 50-48 a war powers resolution directing Trump to halt military operations — a narrow margin, but a remarkable one, requiring enough Republicans to cross the aisle and rebuke their own president on a question of war. The House had already passed a similar measure earlier in the month. Congressional anxiety about an open-ended Middle East commitment with no clear endpoint was hardening into action.

Ben-Gvir's declaration arrived precisely into this moment of American retrenchment. If Washington was losing the will to act, Israel was signaling it would not. The alliance that had sustained the campaign was showing its fractures — and Israel was preparing to move forward without waiting for it to heal.

Israel's National Security Minister Itamar Ben-Gvir made clear on Tuesday that his country would not wait for American backing to confront what he sees as an existential Iranian threat. The responsibility to act, he said, falls to Israel alone. His statement arrived as the broader American commitment to the conflict that ignited on February 28 was visibly fracturing—both in Congress and among ordinary voters.

President Donald Trump, meanwhile, was celebrating what he framed as a victory. He announced that 19 million barrels of oil had moved through the Hormuz Strait on Monday, a figure he called an all-time record. In his telling, the numbers proved the point: oil prices were falling, the world was safer, and the conflict was working as intended. He posted the claim on Truth Social with the confidence of a man watching his strategy vindicated.

But the polling told a different story. A Reuters/Ipsos survey found that only one in four Americans believed the war had been worth its cost. Just 23 percent of the country—and only half of Republicans—thought the United States had emerged in a stronger position relative to Iran than it held before the fighting began. Thirty-five percent believed America was now weaker. The rest were uncertain or saw no meaningful change. The gap between Trump's narrative and public perception had become impossible to ignore.

In the Senate, that gap translated into action. On Tuesday, lawmakers voted 50-48 to pass a war powers resolution directing the president to halt military operations against Iran. The measure had already cleared the House earlier in the month. The vote was narrow, but its significance lay not in the margin but in the fact that it happened at all—that enough Republicans had joined Democrats to rebuke their own president on a matter of war and peace. The conflict that began four months earlier was becoming increasingly unpopular even among Trump's own party.

The resolution reflected a broader congressional anxiety about an open-ended commitment in the Middle East with no clear endpoint and mounting costs that Americans were unwilling to bear. Lawmakers worried, too, that any ceasefire with Tehran would be fragile at best, a temporary pause rather than a durable peace. A majority of those surveyed said they doubted a truce would hold.

Ben-Gvir's statement, then, arrived in a moment of American retrenchment. Israel, he was signaling, could not afford to wait for Washington to rebuild consensus or for diplomacy to take hold. The nuclear question was too urgent, the threat too immediate. If the United States was losing the will to act, Israel would have to find it elsewhere—in its own military capacity, its own strategic calculus, its own willingness to strike. The implication was stark: the alliance that had sustained the campaign might be fracturing, and Israel was preparing to go forward without it.

Why is Ben-Gvir saying Israel has to act alone now, specifically?

Model

Because American support is collapsing. Congress is voting to stop the war, most Americans think it wasn't worth it, and Trump's political capital on this issue is evaporating. Israel can't count on that backing continuing.

Inventor

But the US is still militarily involved, isn't it?

Model

For now. But Ben-Gvir is reading the room—the Senate just voted to halt operations, even if narrowly. He's saying Israel can't wait for American consensus to rebuild. The nuclear threat doesn't pause for politics.

Inventor

What does "act alone" actually mean in practical terms?

Model

Likely unilateral strikes on Iranian nuclear facilities. Israel has done this before. It means moving without coordinating with Washington, without waiting for approval, without the cover of American military support.

Inventor

Is Trump actually claiming victory here, or is he worried too?

Model

He's claiming victory—19 million barrels of oil, prices falling, world safer. But the polling and the Senate vote suggest he's isolated on this. His own party is turning against him.

Inventor

What happens if Israel strikes without US backing?

Model

It escalates the conflict dramatically. Iran responds, regional allies get pulled in, and the US has to decide whether to support Israel retroactively or distance itself. Either way, it's a rupture.
