I hope that if WW3 happened, I'd be brave enough to stay and fight. I love Britain & I'd hate to leave it or see it invaded by Putin.
However, at the same time I'm wondering about the recent rush of articles suggesting conflict with Russia is inevitable by around 2030 and that civilians need to prepare to be conscripted to fight if NATO is attacked. I'd always thought Britain being land-invaded was fairly unlikely, but being called up to fight in a NATO war widens the options of what might happen.
Countries that are less likely to be involved include Austria, Switzerland, New Zealand, Republic of Ireland. I don't particularly want to move to any of these. If call-ups are likely to be imminent in about 4 years, I don't know..
The country I've always thought I'd move to if I did move is Poland (where I have family ties)- but of course that's far more likely to be involved in a potential war!
