Cause Iran's whacko leaders don't seem to think he can do much against them with low public approval and a Congress who runs from him, rather than to rally him. Their language shows that they aren't at all fearful of the USA (right now).
This has been the case since 1979 and a succession of Presidents. If they were fearful of Reagan then they would not have had their Hezbollah surrogates attack our troops in Beirut.
If we were to have instilled the fear of the USA in them , in '83 we should have extracted a big pound of flesh for the Beirut attack and the embassy issue.
The big difference now is their leadership is infatuated with an apocalyptic scenario and the return of the 12th Imam.
As a nation, they're leaders are ready now more than ever to commit national suicide for their delusions.
Plus they are rattling off at the mouth because they don't have the Soviet Union proxy to hide behind. They talk like the punk who is puffing up his chest but inside knows he is about to get his ass whipped.
Iranian tough talk is NOT ABOUT THE PRESIDENT'S POLLS. It is about their awareness we can kick them back to the second century BC. They will be stopped.
Iran's wackos were raised in a closed society and have no perspective from which to judge world events. Bin Laden also thought we would put our tail between our legs and retreat after 9/11. He was as correct as the Iranian mullahs will be if Israel is nuked.
Say what you want about the President, he does not govern by polls, and the bombs would fly before the American people or the Congress had time to think about it, much less offer an opinion.
If W is still President when Israel is nuked, we will nuke Iran. Bet on it.
