So, Bill, you'd want us to have left our troops there, dying, for an indefinite period of time pursuing, "nation-building." I bet you think S. Vietnam also was ready to be well-led by its generals and scum, too? "Way too early." One has to pause reading that. I assume you have some understanding of how much the deficit was blown-up by that war (by all wars, actually)? Or is a deficit not applicable in a war? Exactly what would an American soldier be dying for in Iraq? Security for Israel?
Carter was career Navy, my friend, when Reagan was a faux cowboy. Enough said.
Russia was tipping over when Reagan took over and perestroika was obviously due to Gorbachev: economic collapse has nothing to do with the wall being knocked down. N. Korea: is it collapsing because of economic hardship? Iran? No. Reagan was not the major figure in the collapse of the Soviet Union, it was Gorbachev. 
Neither Reagan nor Bush avenged the massacre of Americans. Does that "coincidence" not tell you anything?
