Yes and soon–in 2012 itself–if you believe New York Times:
After speaking with many senior Israeli leaders and chiefs of the military and the intelligence, I have come to believe that Israel will indeed strike Iran in 2012.
Two thoughts:
One, what will happen to oil prices and the world economy if Israel indeed attacks Iran?
Two, we can only imagine the diplomatic pressure on India (and China) to reduce oil imports from Iran. India and China are two major importers of Iranian oil who have refused to curtail purchases from Iran after the recent sanctions by the US and the EU. Indian policy makers have little wiggle room to sustain economic growth if a big shock hits the world economy.
