I haven't seen anyone elsewhere point out that maybe he is onboard. It may not be the case, but there must have been some convincing information to convince various countries to do this, and our evidence against is the departure site and the president's word. There is an ongoing tension between a block of south American countries (see the Argentinian tweets on github), and the USA. Non-violent aggressive acts like this, or conversely offering asylum, are part of it. The US has strongly resisted any external influence on the rest of the continent, as a doctrine. Now a block is forming locally, they will go to great lengths to resist it. I think an explanation for why the block is upset in turn can be found in the leaked cables.
