I grew up in the 1970’s and was vaguely aware of the terrorism in Europe. I’d guess even people not born then at least know of the attack on Israeli athletes at the Munich Olympics (1972). I saw coverage of that tragedy live the day it happened.
Terrorism attacks occurred periodically throughout Europe throughout the 70’s . Thankfully we didn’t have a 24/7 news cycle to incessantly trumpet the tragedy day after day. We had Harry Reasoner each weekday evening from 5:30 to 6:00pm delivering the day’s news and newspapers.
Events that I recall…
London had numerous IRA bombings. The assassination of Lord Mountbatten in 1979.
Italy had the Red Brigades
Germany Red Army Faction, The Revolutionary Cells.
Groups opposing Israel The Black September Organization (BSO), The Popular Front for the Liberation of Palestine (PFLP) and many others
There were far too many other terror groups for me to remember.Daily Beast wrote an interesting article How Europe Defeated 1970’s Terrorism .
In terms of danger and deaths. How does it compare today with the ISIS terror cells?
