Seems more GD or IMHO.
a) many Americans aren’t aware of this connection
b) many Americans, even if they are aware of who’s training Colombian guerillas, could quite frankly care less about what goes on in Latin America
c) many Americans supported/still support the IRA. There are more here who claim Irish descent than there are people in Ireland. Where do you think most of the IRA’s money came from? My sweet, senile, 88-year-old Irish-American aunt gave thousands and thousands of dollars to the IRA over the course of her life. Some people who gave cash did it knowing full well that it would buy arms to fight the British, while others deluded themselves into thinking it was merely going to aid women and children, etc., who were left poor, homeless, hungry, etc., by the violence (thanks to the Brits, of course).
I would say, no, many Americans have not changed their opinion of the IRA, though I think everyone is, frankly, relieved that they’ve eased up since 9/11, since it would have required a great many U.S. supporters of the IRA to reexamine their positions.
Then there are those of us who think the people in the IRA are a bunch of terrorists, pure and simple, and, quite frankly, don’t see what the fuss and push for independence/etc. is all about, as Ireland/Northern Ireland/Scotland/Wales/England are all the same to us here, and not qualitatively different than, say, New England/the Mid-Atlantic states/the South/the Midwest/the Southwest… so why can’t you all just get along?
