We need to be reminded that actions have consequences. How the seizure of the US Embassy was dealt with in 1979 had consequences, and Ahmadinejad was on the scene.

How this president has interacted with the Prime Minister of Israel has consequences. What Israel has to lose and what they have to gain play large in this scenario.
