I wish I could believe that. Frankly, the PC crowd has such a long track record of ignoring reality that its hard see them coming to their senses, even if the Jihadists used nukes on us. My money is that they would wring their hands over the destruction, BUT would keep right on jabbering about how racial profiling, military trials, and forced deportation is STILL the greater evil.
More likely, in such a scenario, the more sensible elements of society would have to declare marshal law and throw both the Jihadists and the Leftists into detention camps. When it comes down to raw survival, both groups are dangers to our society in their own way.
Their isn't going to be any time for ignoring reality or anyone coming to their senses once the 1st nuke goes off. The response triggers will be pulled without any time for PC to interfere and the end result will be the end of Islam and a large part of the rest of the world. The war on terror will have been won at a price that should never have been paid. There is still the chance we shall be the trigger pullers and I relish the thought of Mecca being turned into glass before a civilized city has to be sacrificed.
