It would have been the 70s and 80s. The 90s being a stretch, right? Has King been there that long?
muslim terrorism is different it is on a international scale USA, Spain, Germany, Israel, Philippines.
The IRA was limited to (correct me if I am wrong) The UK.
They just want to make another issue of something that has died out.
The IRA bombed and killed British servicemen in Germany and murdered two Aussies in Holland because they ‘looked British’. They were also famously stopped by the SAS from setting off THAT bomb in Gibraltar.
