65. Since 1954 the US military has intervened over fifty times in Central America,

usually to depose leaders we disapproved of, back those who would do our bidding and, most importantly, prop up US corporate interests.  American men, money and arms flooded into Central America, rightwing death squads were organized and US-backed dictators employed all manner of terror, torture and murder to silence their own people. 

Those conflicts devastated economies, displacing generations of Guatemalans, Salvadoreans, Nicaraguans, Hondurans and many others.  This long, bloody history might explain why migrant men, women and children cross the southern border trying to escape the horrors of American foreign policy.
