I obviously don't deny that the USA committed terrible abuses in Latin America, but I have yet to see the widespread resentment you speak of; not everybody walks around with a copy of The Open Veins in their pocket down here. Latin Americans can be as ignorant or apathetic of history as anybody in the USA.
I am not a Chavez supporter, but the claim that he or many Venezuelans "hate the USA" lacks nuance to say the least. If that were the case, Johann Santana would be reviled as a traitor for playing baseball in the USA, rather then being received by Chavez as a hero.
