Can Obama turn Latin America into a friend?

Today we find Obama in Trinidad for a "Summit of the Americas - minus Cuba." Last time in Argentina the locals rioted when George Bush showed his face.

What can Obama do to improve US-LA relations?

1. End Cuba embargo

2.support the governments in Venezuela, Brazil, Ecuador, et.al. instead of trying to destabilize them.

3. 100 million impoverished Mexicans--can we help?

4. Help Haiti--you say you do but the country is a basket case/failed state.

5. Close all US military bases in LA-they are fronts for right-wing US corporate power.
