As a 55yo Brit, I'm going to say I'm very much in the "it's bad, shocking, should not have happened" camp, but doubt there is a speck of difference that I personally could make, in relation to any of these conflicts.
FL "Studying conflicts, genocides, wars is crucial to understanding society and trying to prevent further conflict." and "I suppose I think that there should be an automatic level of knowledge of conflicts/politics etc from one's own lifetime and region"
I accept the first statement but (as my line of work probably has no likelihood of affecting any conflict) prefer to spend my time on other things.
In the case of the second statement, I would classify my "region" of interest as being the UK primarily, and everywhere else, if conflict might lead to the UK being a target, or affect us (eg WW III being started by China or Russia, against the USA, or perhaps between themselves).
I have not bothered with a daily newspaper since I was 20, rarely watch TV news broadcasts, but do listen to some of the radio news (BBC R 4), though it gets boring when the same clip gets played on news at 1300, 1700, 1800, 2200 and then again at 0000 (!)
I am often beyond caring who said what, to whom, and the implications, if there has been nothing "new" in the past 4 hours.
