No. The most dangerous enemy are not the air heads watching American idol. All nations everywhere has had peasants, even a democracy can survive.
The most dangerous are the "enemy within". In that I include both closeted moles and terrorist cells of various Islamic groups, as well as their institutional supporteres like CAIR. Also, and possibly even more dangerous, are the American hating "liberals" and "porgressives" who view G.W. Bush as more of a threat than Al Qieda. This includes everyone from the ACLU to Rosie. They are dangerous in various levels because, at root, they seek the failure of America and the victory of our enemies. They are constanly burrowing under the foundations to bring their dream about.
They were all supporters of the USSR in the Cold War and did everything from spying for them to supporting unilateral disarmament as designed by the KGB (under the term "Nuclear Freeze") through-out that conflict. It is only by the grace of god and the strength of a very few good men, led by the heroic Ronald Reagan, that they were not successful.
It is unlikely we will be so lucky twice as to defeat both a strong external enemy and massive internal subversion in support of it without blood being shed.
Great article and interesting thread.
