Thinking prudently about Egypt is not 'fear mongering'
Before there was Lenin, there was Karensky.
Before there was Hitler, there was Von Papen.
Before there were Soviet satellites in Eastern Europe, there were "provisional coalition governments" where Communists were not a majority.
Before there were the Sandinistas, there was a "Unity government" in Nicaragua.
Before there were radical Islamists in Tehran, there was a "moderate" Islamic government headed up by President Banisadr.
The point is simple; men with guns who are ruthless enough and determined enough can emerge from chaotic political situations to rule.
I am sick to death of being told by the left that bringing up the possibility - not the certainty, or even the probability - that the radical, anti-American, anti-Israel, anti-Semitic Muslim Brotherhood can emerge from the chaos in Egypt and takeover the government is fear mongering or ignorant. It is neither. It is something we conservatives take pride in - being prudent.
You can bet the Obama administration is losing sleep over the possibility. The catastrophe for the world if those Nazi-inspired thugs end up muscling out sheep like El Baradei in any sort of "Unity Government" is literally to horrible to contemplate. It would almost certainly mean an abrogation of the Camp David Accords which would increase the chances of war between Israel and Egypt significantly (There has already been discussion in the Israeli press of moving back into the Sinai if the treaty were held in abeyance.)
I would say to my friends on the left, take off the blinders and acknowledge the world as it is. Any government that includes the Brotherhood will be at risk of being overthrown. History has shown us how easy it is. Not to address the possibility is rash and, dare I say, imprudent.
