“What makes you think so?”
Israel will have a very narrow window of opportunity to hit Iran, and the Winter months are the optimum time. Israel knows and accepts that it is on its own vis-a-vis Iran, and that the ObaMugabe administration would not only not help, but would actively try to derail such an attack. Washington pretty much goes into hibernation in the Winter when it is not up to mischief. That, plus the likelihood that the U.N. is gearing up to bitch slap Israel (a nuisance for Israel, but no real threat; still, it would have to deal with the mosquito bite, and that’s an annoyance Israel would like to avoid during such an existential action); and, of course, Iran is now at the point of weaponizing a nuke and its delivery systems. Israel is facing an imminent existential threat, and it will act accordingly.
But, what I was trying to get at is whether you had any specific sources.
