Strikes on Iran mark Trump's biggest, and riskiest, foreign policy gamble

With his unprecedented decision to bomb Iran's nuclear sites, directly joining Israel's air attack on its regional arch foe, US President Donald Trump has done something he had long vowed to avoid — intervene militarily in a major foreign war, reported Reuters. The dramatic US strike, including the targeting of Iran's most heavily fortified nuclear installation deep underground, marks the biggest foreign policy gamble of Trump's two presidencies and one fraught with risks and unknowns.

Trump, who insisted on Saturday that Iran must now make peace or face further attacks, could provoke Tehran into retaliating by closing the Strait of Hormuz, the world's most important oil artery, attacking U.S. military bases and allies in the Middle East, stepping up its missile barrage on Israel and activating proxy groups against American and Israeli interests worldwide, analysts said.

Such moves could escalate into a broader, more protracted conflict than Trump had envisioned, evoking echoes of the "forever wars" that America fought in Iraq and Afghanistan, which he had derided as "stupid" and promised never to be dragged into.

"The Iranians are seriously weakened and degraded in their military capabilities," said Aaron David Miller, a former Middle East negotiator for Democratic and Republican administrations. "But they have all sorts of asymmetric ways that they can respond... This is not going to end quick."

In the lead-up to the bombing that he announced late on Saturday, Trump had vacillated between threats of military action and appeals for renewed negotiation to persuade Iran to reach a deal to dismantle its nuclear program.

A senior White House official said that once Trump was convinced that Tehran had no interest in reaching a nuclear agreement, he decided the strikes were "the right thing to do."

Trump gave the go-ahead once he was assured of a "high probability of success," the official said - a determination reached after more than a week of Israeli air attacks on Iran's nuclear and military facilities paved the way for the US to deliver the potentially crowning blow.

Trump touted the "great success" of the strikes, which he said included the use of massive "bunker-buster bombs" on the main site at Fordow. But some experts suggested that while Iran's nuclear program may have been set back for many years, the threat may be far from over.

Iran denies seeking a nuclear weapon, saying its program is for purely peaceful purposes, said Reuters.

"In the long term, military action is likely to push Iran to determine nuclear weapons are necessary for deterrence and that Washington is not interested in diplomacy," the Arms Control Association, a non-partisan US-based organization that advocates for arms control legislation, said in a statement.

"Military strikes alone cannot destroy Iran's extensive nuclear knowledge. The strikes will set Iran's program back, but at the cost of strengthening Tehran's resolve to reconstitute its sensitive nuclear activities," the group said.

Eric Lob, assistant professor in the Department of Politics and International Relations at Florida International University, said Iran's next move remains an open question and suggested that among its forms of retaliation could be to hit "soft targets" of the U.S. and Israel inside and outside the region.

But he also said there was a possibility that Iran could return to the negotiating table — "though they would be doing so in an even weaker position" — or seek a diplomatic off-ramp. In the immediate aftermath of the US strikes, however, Iran showed little appetite for concessions. Iran's Atomic Energy Organization said it would not allow development of its "national industry" to be stopped, and an Iranian state television commentator said every U.S. citizen or military member in the region would now be legitimate targets, reported Reuters.
