I think Israel is getting wary of team Obama throwing them under the bus, and will soon make the choice of to go it alone against Iran. I do not think Obama will give them much ie intel or commodity to not protect their existence.
Imagine if Mexico was fanatical, citing they want to commit genocide against US citizens, and wipe us off the face of the map while working on nuclear weapons and ballistic missiles. At what point would you want our politicians to strike to save us from anhilation even if Canada did not approve. I feel for the people of Israel as well as the innocent civilians in Iran.
Some politicians make it out like both sides have good arguments, or valid points in the debate. But let us be clear, one country merely wishes to exist, the other wants to wipe that country off of the map. It could be sooner or later, but the time to avoid nuclear war is shrinking rapidly.
