I don't see it as that big of a deal. From the U.S. Embassy site:

FORWARD OPERATING LOCATION (FOL) – MANTA, ECUADORFOL MISSION
"The mission of the FOL is to help Ecuador protect the sovereignty of its territory against the transnational crime of drug trafficking. We are supporting efforts in the Eastern Pacific to intercept the flow of drugs that threatens the health, safety and economic stability of our hemisphere. Our cooperation with Ecuador is producing positive results." --U.S. Ambassador Linda Jewell
In 1999 the U.S. and Ecuador signed a bilateral agreement that permits the U.S. to use a portion of the Ecuadorian Eloy Alfaro Air Force Base in Manta as a Forward Operating Location (FOL) to conduct counter-narcotics flights. The agreement expires in November 2009.
The FOL is an important part of the cooperation between the U.S. Government and the Government of Ecuador to combat the transnational threat of drug trafficking and protect Ecuador, its citizens and institutions, from the negative impact of international drug traffickers.
The FOL is not a U.S. base. It is located within the Ecuadorian Eloy Alfaro Air Force Base and occupies less than 5% of the physical territory of the Eloy Alfaro Base.
The FOL consists of parking spaces for up to 8 unarmed aircraft (4 large and 4 medium-to-small) which fly counter-narcotics aerial surveillance missions, focused on the Eastern Pacific maritime zone. A handful of small buildings support the crews and staff who service these flights (dormitories, a cafeteria and office space)
