Thank you both for the historic background that led to the present 'troubles'.
We were never taught such history. Equally sadly, during my schooling years (and reinforced by a lifetime of media bites), history was never presented as being a vital early warning system, which it can be.
My mental 'media sound bite' summary of ME politics and violence is:-
Everyone who takes sides in a conflict, is escalating the conflict from local atrocities, to potential world wide atrocities.
Unless, of course we all take sides with the biggest bully. Really quickly.
Taking sides is the opposite to mediation, in any disagreement.
