What are your thoughts?
Given the rhetoric of the Iranian madman, I would have to assume that any missile launched from Iran targeting Israel could possibly be armed with a nuclear weapon. There have been a lot of "intelligence estimates" as to when Iran could build nukes and then incorporate them into a missile system. These estimates are all over the map, and the spy agencies are far from infallible. Also, with the amount of cash that Iran has from their oil revenues, they could possibly have bought a nuke from North Korea or from the Russian mafia, etc.
I would hope for the good of the world, that Israel wouldn't "launch on warning", and wait for confirmation they were actually under nuclear attack. The Israeli leadership would have to be strong and decisive, traits I haven't seen much of from Olmert. I hope they've war-gamed the options and they have a plan.
At the least, it should give Israel the leeway to strike Iran's nuclear facilities, hopefully knocking them out. If Israel was incapable of knocking out the facilities, I would hope that we would lend a hand, at least covertly.
