Things aren't great in Europe. If you want to delve into intercontinental nuclear war, please start another thread. This is about possible wider conventional war in Europe, outside of Ukraine alone.
Putin clearly is right out of Soviet Union central casting. He is surely more like Stalin and Brezhnev (and so many other hard line Soviet era leaders) and less akin to Gorbachev and Yeltsin. Maybe he will back down but it has not happened yet.
Before he reaches out with nukes I can envision Putin attacking, possibly with missiles or other conventional armaments, perhaps the Baltic states, or Poland, or God only knows where else or what other former Soviet satellite countries. There are a number of possibilities. Regardless what Putin might attack next, it would come down to a wider, growing, war in Europe.
I don't mean to be heartless or unconcerned with the suffering of those on the receiving end of Putin's aggression. But I do wonder about the impact on our USA home markets and on interest rates here in particular. And of course the danger of our being drawn into wider conflict hangs over everything. Heck, we're already involved just with Ukraine. But I'm unaware of much economic or interest rate impact so far. That could change I'm afraid if European conflict expands. It was scarcely more than one hundred years ago that European war started small and grew into WWI.
I don't have a good handle at all on what might happen or on the impacts. Can tell you I am comfortable not making five year CD commitments right now. There is just too much uncertainty.
