The answer is clearly "NO!" Take a look at Bahrain, Egypt, Lebanon and the Palestinians and you could come to no other conclusion. Despite all the propaganda to the contrary the U.S. is interested in its own interests—read
business and oil—and not democracy. The U.S. has spent years and years supporting despots and dictators throughout the world while cheer leading "democracy." Wave a patriotic flag and the masses will not notice the falsehoods and propaganda, so the story goes. I think Glenn Greenwald has an excellent piece summarizing at Salon
here.
