For Trump, one advantage of Soleimani’s assassination is that the Iranians will be more cautious about launching limited attacks on the US and its allies, though this isn’t to say that they will cease altogether. Iran cannot permanently de-escalate as long as sanctions continue. The intensity and length of the crisis means that accidents are likely to happen, as demonstrated by what appears to have been the unintentional shooting down of a Ukrainian passenger plane. At the same time, Trump and his administration are peculiarly ill-equipped to judge the likely outcome of any escalation of the conflict, or predict how the Iranians are likely to respond. This makes blundering into war a more than usually likely outcome. Iran has drawn the greater profit from the crisis so far, since Soleimani’s death goes some way to re-energising the nationalist and religious credentials of the regime: Trump’s policy of ‘maximum pressure’ and economic sanctions is now less likely to force Tehran to negotiate what would amount in effect to a capitulation. In Iraq, it is too early to say whether the demand for revolutionary reform expressed in mass street protests will be marginalised or capsized by the crisis, but it will certainly be weakened, perhaps permanently.
