Was the U.S. Involved in Killing the FARC-EP Leaders?

While virtually every country in Central and South America, including the Caribbean, has waged in on the debate of the Colombian state conducting an illegal military campaign within Ecuadorian sovereign territory, resulting in the deaths of various high ranking officials in the Revolutionary Armed Forces of Colombia-People’s Army (Fuerzas Armadas Revolucionarias de Colombia-Ejército del Pueblo, FARC-EP), the United States have remained virtually silent. Such silence from the US is quite perplexing consdiering the administrations of Ronald Regan, George H.W. Bush, Bill Clinton, and George W. Bush have wielded a twenty-two year old assault on this insurgency movement.
