Well, normally, I'd agree on this that Russia attacking Poland would be a really bad idea for Russia. BUT, remember, NATO is also a paper tiger w/o the US. And the US is being led by two of the most incompetant men that have ever held the position of POTUS and Sec of War.
After all, we just went over and attacked Iran... We dominated their military and took virtually no losses while doing it. Yet somehow we are arranging for Iran to get 300 BILLION to rebuld. They are keeping all their Nuclear material, their ballistic missle program, they can sell oil again, AND all their frozen assets are going to be released. BUT in all fairness to the Deal maker in Chief, Iran DID agree to sit down at a later date and DISCUSS inspectors.
So MAYBE this Russia attacking isn't so crazy. After all, tangling with the US sure did work out for Iran.
