That was my guess too. In fact, it is my firm belief that is was the gradual retreat of religion since 1800s --- both Christian and Jewish --- that allowed socialism (invented by the French at that time) to creep in.
I am both optimistic and pessimistic: optimistic that we will prevail in the end, and pessimistic that that will not happen until we incur catastrophic costs. We are already doing so: who will return the thousands of our fellow Americans that dies on Sep 11? Terrorism had been going on in Europe since 1970s --- did we pay attention? In 2000, an extremist was arrested In Turkey on the suspicion (proven) that he wanted to fly an airplane into the mausoleum of Attaturk --- a symbol for the Turks far exceeding in importance our WTS to us. Algerians were arrested in France (after storming the airplane) on the way to fly an airplane into the Eiffel tower? Did we pay attention? Knowing this, I find no excuse for all of us --- myself included, of course --- for losing 3,000 thousand people that September. And half of the country is still not clear; they want to "explain" themselves to the terrorists and then sing songs together around the campfire, united in brotherly love. We will lose more, I am afraid.
