At this point it is (fortunately) not Biden who gets to decide what happens with this war.
As the the Russian offensive bogs down it becomes increasingly likely that the Poles will join the fight and cross over to defend civilians in Western Ukraine.
“As the the Russian offensive bogs down it becomes increasingly likely that the Poles will join the fight . . .”
At least the Poles and the other former Eastern Bloc nations see that the Russian invasion of the Ukraine is a European problem that requires a European response. Perhaps the other so-called Grandees of Europe will listen to the Poles and join the fight. As for the US, if Biden is so concerned with preserving territorial integrity then he should look to our own southern border, not one located almost 6,000 miles away. Likewise, if Biden feels the need to sanction Russia then stop buying its oil and natural gas. Without that, the other sanctions are meaningless.
