The assassination of Qasem Soleimani has plunged Iran and the United States into their most serious confrontation since the hostage crisis in 1979.

President Donald Trump's decision to kill Soleimani removes one of the most obdurate and effective enemies of the US, and delivers a blow to the heart of the Islamic republic of Iran. It is also a dangerous escalation in a region that was already tense and full of violence.

The killing at Baghdad airport has increased tensions sharply, creating fears of a slide into an all-out war. That is no certainty. Neither the Americans nor the Iranians want one. But the crisis brought on by the killing of Soleimani - and a senior Iraqi ally - amplifies the chances of a bloody miscalculation.

Iran has sworn vengeance. That threat has to be taken seriously. Soleimani was at the core of the regime, and a talisman for Iran's hardliners. They will want to get even, perhaps more than that.

Proxy forces

Despite arms embargoes, Iran has developed a modern arsenal of rockets and missiles. But if it wanted to use them against US forces as part of a reprisal, Iran would risk making matters worse.

An act of war to answer that of the US - for example attacking US ships in the Gulf - would risk provoking a devastating response. Iran's oil refineries are on the coast and would be easy targets for the vast firepower the US has in and around the Gulf.

When Iran retaliates, it is likely to follow Soleimani's own indirect tactics: so-called asymmetric warfare, spurning an attack through the front door for one through a side window.

Soleimani cultivated a range of well-armed militias, which give Iran options short of a head-to-head confrontation with the Americans which it would only lose.

The Americans will now be looking at their most vulnerable deployments in the Middle East. One is the small force in Syria.

Calculated risk

A big question is why the Americans chose now to kill Soleimani.

He had been a thorn in their sides since at least the US invasion of Iraq in 2003. He made sure Iraqi Shias raised, trained and equipped militias which became effective and ruthless fighters against the US and its allies.

The Americans and their allies in Israel and the West have tracked Soleimani closely for years. It's likely that he has been in their sights before.

The fact that this time the Americans pulled the trigger suggests that President Trump believes the reward is worth the risk, that the Iranian regime has been so weakened by isolation, economic sanctions and recent demonstrations that it will rage but not offer a serious strategic threat.

But it is not at all clear whether the assassination fits into a coherent US strategy, and such an assumption could be dangerous and wrong.

Soleimani was a colossal figure inside Iran. He was its strategic mastermind. Perhaps he left a plan of steps to take if he were killed.

This assassination at the start of a new year and a new decade might turn into another Middle Eastern milestone, touching off another sequence of bloody events.

To begin with, the Iranian regime must now be planning its answer to his death, to show that the position Soleimani spent so long creating outside its borders in the Middle East can be defended.
