As it appears Iran's attack on US facilities in Qatar has concluded, we've just been hearing from our correspondents about what could happen next.
Our US correspondent Mark Stone, in Washington DC, says it's still a moment of "huge, huge jeopardy", with potential for miscalculation on either side despite Iran appearing to have warned the Qataris in advance.
In the longer term, though, Stone says the question is: "What is the plan for the day after?"
He adds Tehran may feel this evening's attacks draw a line under the American strikes on its nuclear facilities over the weekend, but the Israelis seem to remain clear "they want to continue with this".
Striking echoes of history
"For Israel, America's actions on Saturday night were not the end of it," Stone says. "For Israel, they want to keep going. To what end?"
Regime change has been floated by Benjamin Netanyahu and Donald Trump, but they "have to have a plan".
There are some "striking echoes of history", Stone continues.
He says America had "absolutely no plan for what came after" its invasion of Iraq in 2003.
"And the consequences of that invasion are being felt today."
Is Netanyahu ready for a protracted war?
Our correspondent Cordelia Lynch is in Tel Aviv, and she explains Israelis are "unfazed" by the daily ritual of running out to the bomb shelters.
Netanyahu "has already warned of the potential for a protracted war at the very least".
"This Iran, he believes, represents an existential threat - this is something he has had designs on for three decades," Lynch says.
"I think the notion of a quick exit from Israel is highly unlikely, and we are not seeing any kind of framework laid out for regime change, any hint of what they plan to do beyond the strikes that they are still carrying out with regularity."
Even Netanyahu's fiercest critics are supporting this operation, but there is "a lot that could happen", Lynch adds.
The lack of US casualties could mean Trump decides not to respond right now, and "there is still a glimmer" of potential for diplomacy.
But the Israeli leadership is pursuing this "with great enthusiasm and gusto".
