Alright, so the US has made mistakes in the past. What do I expect of them now? Well, first of all to stop making those same mistakes, and secondly to help repair the damage that they have done. And evidently, they're interested in neither.
Quick example. In the 70's, the CIA staged a coup in Chile and overthrew Allende, the democratically elected President, becuase his policies threatened Pepsi Cola's business in Chile. They installed Augusto Pinochet, who ruled the nest several decades with an iron fist and caused great harm to the Chilean people.
Fine, that in the past.
However...
...they're at it again. President Chavez in Venezuela was elected with massive support in 2000 to serve a 6 year term. Now, Washington is trying to destabilize the government by alleging that Chavez tampered with election ballots. Keep in minid, these are the same people who had their hands in the 2000 election fiasco, and I use the word election loosley. Washington is doing this because Chavez in not being a good yes-man and obeying their commands to liberalize the economy, which would wreak havoc on Venezuela's population. By trying to force Chavez out, they want to put in a more US friendly President, one who will look after the rich and the corporations instead of the people. Already in the past, the US has staged a coup attempt with the backing of Venezuela's elite, and failed.
So you see, America has not realized its mistakes, because in their view (government's mostly, not people's) they have made no mistakes. Only such decisions as protected the interests of America corporations. This is to them, a fair decision, despite the massive suffering that they have inflicted worldwide.
