Plus, the ‘are we fucked?’ type-comments are rather dismissive of the fact that millions of people around the world are living under daily bombardment, with no access to clean water and no food security. I.e. Yemenis, Syrians, Iraqis, Somalians, Ukrainians in Donetsk/Luhansk etc.
Yet Westerners only care when they briefly think it might affect them - which it won’t by the way. If there is a “WW3” it will be fought in the Middle East and it will be Middle Easterners who suffer, as always.
In the UK, or the US, a small number of people may be killed by terrorists radicalised by this experience, but those numbers will pale in comparison to the price paid by the Middle East.
