Watch part two
This week Inside USA heads south for a Latin American take on the influence of the US in the region.
We travel to Venzuela, Colombia and Argentina to look at the power dynamics, which have changed dramatically over the last decade.
Today, in most Latin American countries - pledging allegiance to Washington DC and its institutions would be political suicide.
As the US influence in the region wanes, America's last major ally is the right wing government of Colombia, where the Bush administration has been trying to nail down a free trade deal.
In the US, it is a controversial deal, with both Hillary Clinton and Barak Obama opposing it.
We report on how that proposed free trade deal is seen inside Colombia.
Inside USA also travels to the slums of Caracas in Venezuela where we find armed militias preparing for what they call an imperialist invasion.
