If parents had felt like that in the sixties - when let's face it things (Bay of Pigs, Cold War, four-minute warnings etc.) were a lot worse than they currently are - then your generation would have missed out. It is worrying that we may breed another generation of "Reds under the Bed" paranoiacs.
You will know that things are bad when the government dusts off "Protect and Survive".
It's interesting that you say that as I can remember the bay of pigs in as much as I knew my mother showed a kind of concern that still haunts me. All I knew was that people were saying something about WW3 and that everyone seemed terrified for some time. I am now in my mid 50s and still it haunts me. What then will children of this generation feel in their lives. They have to rationalise a pandemic, a war - senseless like no other, global warming, Trump, the Chinese threat and all the array of other reasons that have motivated to protest in a very public way? I may have witnessed some of these things throughout my life, but never have they seemed so pronounced or accented.
It's shite and I want to get off.
It is interesting that Putin is still closely following the GWB/ Blair playbook (as modified by the use of Trumpian "fake news" klaxons): "they have WMD!", "regime change", "coalition of the just" etc., but our media is still completely oblivious to the irony.
When we "took down a local warlord" it was obviously in the name of peace, when they "kidnap a local mayor" it is a war crime.
When we hit a hospital/ wedding party/ children's school, it was "unfortunate collateral damage", when they do the same ...
I do see your points and have always struggled with irony of it all. However, this does seems to be by the will of just one man as it is literally one brother having to kill another. There does not seem to be a perceived "them and us" in this conflict. It's just killing without a goal.
