NSA Director, Congress and Monitoring
Thanks to Bruce Schneier for pointing out the testimony from NSA Director Michael Hayden, in which he talks about how the NSA worked pre-9/11 and post. And, as Bruce pointed out "...[he] tells Congress that they can best help him by going back to their constituents and finding out where the public wants to draw the line between liberty and safety."
However, non-interventionism (the clear view of the world held by George Washington, et. al.) is the best way forward toward peace and progress.
Non-interventionists fully engage the world in trade, travel, and commerce. Non-interventionists DO NOT invade other countries (Russia, 1917: for which America was never forgiven), they do not prop up dictatorships (Viet Nam, Korea), they do not bomb drug factories in the Sudan (you know who, when).
Non-interventionism says, "We're here to do business with you, let you visit (and even stay, if you'll become a citizen), visit you in your country, be friends with you if you'll do business with us and let us visit you. If you invade our homeland, blow up our buildings, or commit suicide with airplanes, we're comin' to get you sucka!"
That's supposedly why the "War Department" changed its name to the "Defense Department." But that happened just around the time the Pentagon began to be used for committing war just about anywhere the President or the gullible Congress wanted to let him commit it.
Isolationism is the policy of a bunch of xenophobic racists (anybody for Charles Lindbergh?). Non-interventionism was American policy for over a century, and created the best and finest country on the world, which then got trashed by the interventionists from Teddy Roosevelt on forward.
The IPCC has purposely engineered a massive scientific fraud.
