After U.S. and Israeli missiles struck Iran’s nuclear sites in June 2025, Tehran responded with a limited attack on the American airbase in Qatar. Five years before that, a U.S. drone strike against Qasem Soleimani, head of the powerful Islamic Revolutionary Guard Corps Quds Force, was met with followed by an attack on two American bases in Iraq shortly thereafter.

Expect none of that restraint by Iran’s leaders following the latest U.S. and Israeli military operation currently playing out in the Gulf nation.

In the early hours of Feb. 28, 2026, hundreds of missiles struck multiple sites in Iran.

But they also come after apparent diplomatic efforts, in the shape of a series of nuclear talks in Oman and Geneva aimed at a peaceful resolution.

Any such deal is surely now completely off the table. In scale and scope, the U.S. and Israel attack goes far beyond any previous strikes on the Gulf nation.

In response, Iran has said it will use “crushing” force. As an expert on Middle East affairs and a former senior official at the National Security Council during the first Trump administration, I believe the calculus both in Washington and more so in Tehran is very different from earlier confrontations: Iran’s leaders almost certainly see this as an existential threat given President Donald Trump’s statement and the military campaign already underway. And there appears to be no obvious off-ramp to avoid further escalation.

What we should expect now is a response from Tehran that utilizes all of its capabilities – even though they have been significantly degraded. And that should be a worry for all nations in the region and beyond.

The apparent aims of the US operation

It is important to note that we are in the early stages of this conflict – much is unknown.

As of Feb. 28, it is unclear who has been killed among Iran’s leadership and to what extent Iran’s ballistic missile capabilities have been degraded. The fact that ballistic missiles have been launched at regional states that host U.S.........
