Well, here are my thoughts on this issue:
A bunch of power-hungry and insane people want MORE power and wealth. In order to get that objective, they must attack Iran (after causing chaos and conflict in Syria). For the 'Power-Group' it is most important that all non-proxy governments in the region will be eliminated, therefore Syria and Iran.
I heard on main stream news that Israel feels 'threatened' by Iran's displays of military might. That is rubbish. Israel military might is stronger than ever, Israel itself possesses many atomic weapons and at this point in time, nobody would dare to attack Israel. So it's all about distortion and deception. Portraying Iran as the agressive war-monger, while Israel has been pushing and lobbying intensively for an 'ok' on an attack on Iran.
Do the Israeli criminal leadership feel any doubts about plunging the world into a nuclear war? No, they are too 'high' on power right now. They don't see or feel anything, except pushing their little war agenda.
The real victims here will be the people - in both countries it will be the worst and the consequences will be felt everywhere. A nuclear war will not do much good for our planet either (or maybe it will because it will rid the planet of a lot of people and this will give the earth a chance to recuperate from the onslaught of human consumption)
