A fair point but, as I said, it depends upon perspective. I live on the edge of the Middle East here, so we feel the effects of disruption and conflict in the area. Don't forget we had 1 million migrants/refugees landing in one year a few years back, many from Syria - and these give Erdogan the chance to use these as a threat if he doesn't get what he wants.I think it’s true that he is much more insular and less likely to invade/bomb. On the other hand, he talks a good game when it comes to bombing countries off the face of the earth with hell-firestorms.
So less likely to get involved in a conventional war than Biden - but IMO the chances of catastrophic nuclear war - whilst remaining small - are greater with an increasingly unstable and uncontrolled Trump at the helm. Take your pick!
The Obama administration was culpable for a lot of that - and that's before we look at Kosovo and the Balkans, and Libya, where Hillary caused a lot of problems.
Thus, I see that as much more of a threat than nuclear Armageddon - you, quite rightly, have different priorities and concerns in the UK.
