If evil was measured on looks instead of the actual committing of evil; Netanyahu would win hands down. And if this man is elected, forget about a Palestinian state, forget about their rights, forget they even exist. Thats Netanyahu for you.
Israel striking Syria or Iran depends on America. Syria is weak, so no point there.
Now Iran is a different story entirely, even if they are militray inferior to Israel now, that won't always be the case. BTW Israel will never go in Iran

That is a war they will lose. If they do attack Iran, they'll only bomb key 'Nuclear sites' and what ever military they have. However, the Iranian state has said they have the man-power to do some damage to Israel. Either way, it is a no-win-situation for Israel, either they'll get bogged down now, or fear a Nuclear Iran. Alternatively Mr America can do the dirty job for them, but their already having difficulty in Iraq and Afgahnistan. Also, this move will further destablise the Middle-east and increase the Anti-American sentiment already present there. I don't know what all the fuss is about, Iran will not indiscriminately Nuke Israel!
My take is that they might not do it, so that only leaves America, which is very unlikely to do it. So, that means they'll do it.
As for when he'll do it, I hope right after he chokes to death.
I'm wandering what the South Lebanon aka Hezbollah will do if Israel attacks Iran.
