Currently the stealth bombers have returned home.
Still a LOT of jets stationed in the area with bases in Syria, Saudi Arabia, Turkey, Iraq and etc.
Unsure if Israel is going to hit their nuke plants or not. (How they can quickly enrich uranium for weapons, enriching for reactor use is different.)
And we (civillians) are unsure if they have any deuterium and tritium or ways to make more. So any nuke they have might be very very dirty.
You need all three elements to make big big bombs and lightweight enough to fit in a missile. (Something we do not want them to do) because just one nuke tipped missile is not going to create enough damage to wipe out everyone....and when dealing with Israel or US the payback is going to be of biblical proportion.
At that size they need to stay with conventional warheads. They won't survive any nuke attack.
