Those american expats -young youtubers or retired workers or expats- mean something else than the convenience life cheaper cost in Mexico? The forgotten Texas war begun like that: first, low but consistent american colonization; second, take the chance to military intervention. The pretext they already have it: innumerable bands of criminals attacking tourists.
Since 2006, is developing "mexican war on drugs". Thounsands of killers and the cartels are more powerful than ever (armed by americans: they are the bad guys -CIA, DEA, FBI, etc). The government of Mexico is so weak and corrupt that it allows these tourists to wander through the country with an expired visa.
