This is not the global economy 100 years ago. There is a huge amount of money invested in Russia worldwide, Russia has huge investments world wide, Russia has massive debt. Everything is intertwined. A large part of tge world depends on their energy and infrastructure. A few thousand deaths and military spending doesn't out weigh that to them
This has already been brought up. We have talked about how the world is more connected now than it was in the past.
However, NATO will still do what it has to do regardless of the financial impact. Germany and Sweden changing decades-old policies and stances so quickly is astonishing.
Putin was likely counting on those dependencies to prevent NATO (especially all of NATO) as well as other nearby countries from moving so quickly and he was also likely not thinking it would take this long to gain control of the Ukraine government.
History is full of warning signs that were ignored leading up to the start of Hitler's blitzkrieg across Europe and the West never wants to see that happen again or the financial market would get much worse as more countries started being forced to pick sides.
While money drives most of the world's policies and actions, there are worse possibilities and countries have learned are worth taking serious financial hits in the near term to avoid catastrophic financial issues in the long term.
The world is more connected now, but some countries still live in the past and fail to understand just how important those connections are. Putin is learning that now and hopefully more countries will see this and realize that attacking countries is just not worth the cost of the eventual global fallout.
