Subject: Re: Trump: Russia Just Made a Mistake
NATO is quite capable of beating-back any Russian hostility, even without the US. From the western perspective, that is a side benefit of Russia's adventurism in Ukraine: their military is heavily degraded. NATO is more than capable of responding; even more so since they have been enhancing their posture after the Russian invasion of Ukraine.

No far, Poland isn't invoking the NATO treaty. Fortunately for Russia.
