That's fine!
Now explain what possible use would having a nuclear bomb be if it couldn't fit in one of their ballistic missiles?
You think they would be dumb enough to put it in a bomber and attempt to send it to blow up in Israel when it would surely be destroyed by Israel the minute it was loaded onto a plane?
Of course it's a moot point, now that Trump has destroyed their entire air force, their navy, their ballistic missiles, their missile launchers, and their missile manufacturing plants!
Maybe they can use a giant sling-shot to launch it, huh?
