"No, this isn't the end of France. The U.S. and Britain would re-invade before allowing a Muslim revolution to overthrow the French Republic"
Only as long as it takes to secure France's Nukes....then after that...leave France to the Jihadists!
Doubtful. If the situation in Europe ever gets to the point where Jihadis are overthrowing governments, the US is going to be involved in Europe again for the long haul. It would be an incredibly stupid foreign policy move on our part to allow Western democracies to be overrun by Islamic fascism.
