I can't believe the embrace of ARENA on here. They were too thuggish for the Reagan officials who supported the Contras.
Today's political party is not exactly the same as the 1980's guerrilla organization. They have moderated far more than the FMLN.
It's a ridiculous double standard to argue FMLN is nothing but a Soviet-backed terrorist organization but ARENA have washed themselves of all past sins.
But yes as pointed out, even the Reagan administration opposed ARENA, and spent much money against ARENA's founder Roberto D'Aubuisson's Presidential campaign, opting to back the centrist candidate of the Christian Democratic Party instead. D'Aubuisson was also linked to a planned coup against a pro-Western government.
