Many unanswered questions after Trump's post

Trump's Truth Social post announcing the Ayatollah's death suggests he already sees this as a victory - and perhaps the start of what would be a relatively quick campaign.
Although he left open the possibility of a lengthier campaign, the week's worth of strikes he mentioned would be shorter than the 12 days of Israeli airstrikes in Iran last year, and far shorter than previous US air campaigns in Iraq in 1991 or Kosovo in 1999.
There are, however, many unanswered questions.
For one, Trump has now suggested - more than once - that he sees this as an opportunity for the Iranian people to "take back" the country.
But he hasn't made clear who exactly he sees running the country if the Islamic Republic in its current form were to fall.
Trump has previously questioned whether the exiled Crown Prince, Reza Pahlavi, has the support needed to govern.
For the administration, any long and protracted conflict is likely to have important domestic reverberations, particularly as the president campaigned on a promise of ending long, drawn-out conflicts abroad.
In the coming days and week, we're likely to hear him and his political allies make the case that this is something different - an example of what he often terms "peace through strength".
