Charon,
Thanks for your thoughts. With all due respect, while your comments about the 19th century history of the Phillipines and Panama are well taken, consider this please.
The United States has no significant territorial ownership interests in the Phillipines or Panama. In the Phillipines, which was absolutley vital to securing victory in WWII, we built massive military facilities. Those all belong to the Phillipinos now. We didn't make them the 51st state. And we closed our military base and gave back to Panama a multi-bllion dollar inter-ocean canal enterprise that is probably one of the largest components of the Panamaniam economy. And I recall the removal of despotic dictators there too.
Respectfully, I reassert that the U.S. does not conquer territory, to expand the borders of the United States, i.e. as Hitler attemped to do, as the Soviets did, and Iraq attempted to do in 1990. The U.S.A. is not imperialistic or colonial. To paraphrase Sec. of State Powell, we only ask for (not take) just enough to bury our dead.
Thanks again for your thoughtful post.
