Globalisation affects terrorism

At one time the IRA used to bomb the British mainland with impunity while enjoying some local sympathy and receiving funds from Irish-American causes. But now that other terrorists have taken over, bombing it is no longer ‘acceptable’ and the IRA has now decided to end violent actions against Britain. It’s like when a new bully shows up in a school, who’s stronger, badder and crazier than the reigning school bully, the incumbent bully realizes that he doesn’t scare and no one fears/cares about him anymore - and so goes and gets a haircut, cleans up his act and tries new things such as becoming a better student.
