Believe it or not The US having military bases all over the place is a good thing for certain countries, just ask South Korea for example. I would be open to let other countries have military bases here but it would be pointless.

I was living in Ecuador as an Expat when President Corea closed the US military base at Manta, this was the biggest US military base on the Pacific coast of South America. When the Americans complained about the closure Corea offered a compromise deal, he would leave the Manta base open with foreign troops on Ecuadorean soil so long as Ecuador was allowed to open a similar base in Miami. The US ambassador was incensed at such an insulting suggestion and President Corea said that now they knew how it would feel to have a foreign base on their sovereign lands, then he closed the base.
