1- Israel DOES have nukes....they are very technologically effective, plus they're "in bed" with the US
2- Iran is not a walk in the park....though I am against Iran's politics (not against Persians as 75th is trying to convince himself) they are a tough opponent.
3- Iran is not one nation, it is a multitude of nations....were Israel to declare war on Iran, it will spring much controversy and opposition
4- Israel will not use any nukes....it doesnt have enough balls to do so....if it did, it will be nuked back.....terror will break lose, and everyone with nukes will arm...WWIII....only after it's over, there will be no war....it's a cold war with the nukes....no one will use them.....
