does he really have the same set of fears as we do, i don't know. i hope our our gov do.
The guy sits like a wally at the end of a 6 metre table to avoid Covid; I don't believe he wakes up in the morning and screams "today is a good day to die" at the mirror. But even if he does the idea of a "red button" isn't reality: neither Putin, nor Biden, nor Johnson, nor Macron, can hit a button and end the world. There is a chain, and everyone down the chain has to shrug their shoulders and go "oh well, I guess humanity had a good ol' knock, time to get the marshmallows and watch the end of the world. Sorry mum" in order to actually start a full scale nuclear war in cold blood.
It is conceivable (although I believe still highly unlikely) Putin would launch "tactical" nukes at Ukraine, but launching against NATO countries, and especially the US, the UK, and France, is a whole different matter.
i think you're prolly right, at least i hope so.
I don't know whether I'm right and wrong, and I am thankful I don't have to make a meaningful choice on this.
