Carvin analysis is so-so academic. Let me educate this educator with raw reality.

America's Age of Terror is the direct result of its policy of military and intelligence intervention in Persian Gulf and Middle East starting about 35 years ago. It began with CIA regime change in Iran, installation of its puppet Sher of Iran. At the time its about oil, monetary and  military dominance. Iran then overthrew the American puppet and installed an Islamic state. Thus began America war on state Islam which spread ever wider to  the entire region. 

Many wars followed as U.S. linked its Gulf/ME policy with Israel national interests. The combined Axis of Jews proceeded to war non-stop on just about every state in the region, from Egypt to Libya, from Syria to Afghanistan. Though it all the Pentagon install ever bigger military force, sold ever more arms.  Business is very good. Oil is good. Control is good. Money is good. Israel is happy. What can go wrong?

BLOWBACK. RETALIATION. TERROR.
