Well, only solution really is to not depend on other countries here. Mexico is large enough to use their own satellites and if they want to do it not alone they can possibly on-board Brazil, Canada and so forth. It is tragic that the USA is so ruthless here that civilians suffer, but at the end of the day the question is how much dependent one wants to be on an increasingly selfish and aggressive USA. Canada understood the problem domain even though it is hard to change (most Canadians live close to the US border, just look at the population density, that deadlocks trade already to a huge inter-dependency); Mexiko has not yet thought this through.
