So why did we have 9/11? Wasn't that before we went to war?
Yes, but it was long after Islamofascism went to war against us. It is vital to recognize that our own Pres Carter's policies of appeasement gave a faltering (since the end of the III Reich) extremist Muslim theocracy the credibility to recruit and develop political power.
The issues of concern to the nonthinking British think tank are of no consequence to Islamofascists. They actively seek a stone age economy with Middle Ages technology. That, perhaps, is the link between Islamofascism and the Eco movement. They are both on the same page regarding technology and the nation state.
As such, both must be viewed as enemies of democracy. The enemy within is more dangerous than the enemy without.
