The conflict in the Middle East is now in its sixth day and is showing no sign of letting up. Israeli and US warplanes have continued to strike targets inside Iran, which has prompted retaliatory attacks throughout the region. An American submarine has also sunk an Iranian navy ship off the coast of Sri Lanka, killing at least 80 people, while Nato defences intercepted a missile heading towards Turkey.

US officials, who initially envisioned the conflict in Iran lasting four to five weeks, are now warning it may go on far longer. “We are accelerating, not decelerating,” Defence Secretary Pete Hegseth told reporters on March 4, adding that “more bombers and more fighters are arriving just today”. We asked Middle East expert Scott Lucas how dangerous the situation has become.

You’ve called this ‘uncontained war’. What do you mean by that?

Once the Iranian regime retaliated, hours after initial US-Israel airstrikes that it was later revealed killed Iranian supreme leader Ayatollah Ali Khamenei, this was no longer just an American-Israeli war on Iran. Tehran, which had refrained from retaliation beyond Israel in the 12-day war in 2025, was taking this across the region.

This was a war in the Gulf states, where Iran fired not only on American bases but also industrial areas, ports and tankers. This was a war in Lebanon, where Israel responded to Hezbollah rocket fire with airstrikes and an expansion of its occupation in the south of the country. This was the possibility of war spreading to Iraq, where the US military and CIA may be supporting Iranian Kurds for a cross-border incursion.

It is now possibly also a war beyond the Middle East.........
