Dark Brandon don't blink. Dark Brandon sends HIMARS.It's finally coming to a head. Even with the unrecognized annexation of occupied territory Russia says it's theirs and they will defend 'their land' with nuclear force. I'm thinking Biden can only blink, back down with added sanctions, and turn this into the long game.
I can't see the US or UN retaliating with catastrophic consequences after Putin's use of a nuclear bomb since he can always launch another one and then another one...
