Oh FFS cut him some slack, 1987 was peak IRA terrorism. THe Enniskillen Remembrance Day massacre happened a month later. There was an issue with Irish-Americans romanticising the IRA too, the band kept seeing it throughout their US tour. People waving IRA flags at previous concerts if I recall correctly. Considering the tensions at the time in Ireland, good on Bono for ranting. I wish we saw more of THAT Bono today, the angry Bono who didn't take shit from anyone.
