Russia isn’t bluffing. The West started Cold War 2 as soon as Cold War 1 was over. The West has been trying to win the second one ever since.
You whole post is BS. Russia never came to terms that it lost the Cold War. Its bitter. It didn’t hesitate to take western welfare, like supporting its space program and allowing it to join ISS. All the time just waiting to let the bully reemerge.
