Why do the US and Israel seem to be fighting two different Iran wars?

As the Iran war enters its third week, there is a divergence between how the United States and Israel conduct their operations against Tehran and what each nation hopes to accomplish. While President Donald Trump and his administration struggle to articulate an overarching goal for the war, Israeli Prime Minister Benjamin Netanyahu has pushed ahead with expanding the front lines of his army’s assault not only on Iran, but across Lebanon and Syria as well. With little end to the fighting in sight, is this still a single war of unified purpose, two separate conflicts being fought concurrently or a bit of both?

What did the commentators say?

The war on Iran may have been launched by Israel and the U.S. “at the same time,” said CNN, but it’s “becoming clear” the two nations have “some differences in how they see the war proceeding.” The pair enjoys a “number of overlapping objectives,” said former U.S. Ambassador to Israel Daniel Shapiro to the outlet. But there remains “some divergence” between Israel and the U.S., which is only likely to increase “as time passes.”

The longer the conflict lasts, the more likely their “endgames and risk tolerance” may differ, said Axios. Trump, in particular, currently stands “more aligned” with the Israeli government’s “maximalist objectives” than many among his own staff. Israeli and American armed and intelligence services are “moving in concert,” although “their targets vary,” with the U.S. focused “almost exclusively” on military targets, while Israeli assassinations and other operations are “intended to lay the groundwork for regime change.”

Netanyahu may appear to be “flying high” after finding an American president “willing to go all the way” with his long-telegraphed war on Iran, but Israeli analysts are “increasingly aware of where the two countries’ strategies” may bifurcate, said The Economist. Netanyahu has been “blunt” about his nation’s wish for regime change in Tehran, even as Israeli leadership has come to feel that Trump’s goals rest “primarily on controlling the flow of oil from Iran.” Israel is “willing to use the war to inflict deeper damage” on Iranian state infrastructure, while Washington “shows little sign of a clear political endgame,” said Bloomberg. Netanyahu is thus “far more likely to favor a drawn-out campaign” than Trump, given the “growing economic and political pressure” the president faces domestically.

At the onset of this war, both Israel and the U.S. “stated their desire to lay the groundwork for regime change,” The New York Times said. But as the war goes on, Trump has acknowledged that a popular uprising “didn’t seem imminent.” Israel would “prefer” to extend their war “for as long as possible, potentially for weeks, to weaken the Iranians,” said Israeli policy analyst Ahron Bregman to Turkey’s Anadolu Agency. Trump, meanwhile, will “seek a way to end this war, especially as oil prices continue to rise.” His goals “did not include regime change,” said CIA Director John Ratcliffe at a House Intelligence Committee meeting.

It is within this context that Israel’s “related but separate agenda” of concurrent attacks on Hezbollah is taking place, said Shapiro to CNN. Netanyahu is waging an “ulterior campaign to try to do significantly more damage to Hezbollah” in the hopes of spurring a “diplomatic process” with, or within, the Lebanese government. Trump generally supports dismantling Hezbollah infrastructure, yet Israel’s operations in Lebanon are “not of the same level of priority for U.S. interests.”

What next?

For the time being, the Trump administration seems publicly comfortable with the U.S. and Israel’s parallel-and-diverging strategies in Iran. The Trump regime “holds the cards” and has “clear” objectives, Defense Secretary Pete Hegseth said Thursday in a press conference. Israel is “pursuing objectives as well.”

Q: Why are we helping Israel prosecute this war if they're going to pursue their own objectives?HEGSETH: We hold the cards. We have objectives. Those objectives are clear. We have allies pursuing objectives as well.

Netanyahu, for now, “appears to be operating on the assumption that Trump shares his goals,” said William Usher, a former CIA Middle East analyst, to Bloomberg. That may be true “regarding the total elimination of [Iran’s] nuclear program, but perhaps not much beyond that.”
