So, your argument is that we need to get involved, because we’re the defenders of democracy? What kind of bullshit is that? Spoken like someone who’s never put on the uniform, been pulled from your family, and had to bury your brothers. We’re not the world’s police force.
To your second point, Poland is a NATO member, so we do have a vested interest in defending them. Even without our help, I’m pretty confident Poland wouldn’t struggle defending themselves from Russia. If Russia tried it would be WWIII, and Putin knows it. He’s not stupid.
Trump doesn’t want the U.S. to get pulled into their regional conflict, (no American should) because then we would be the ones escalating into WWIII. Russia and Ukraine hate each other, and Russia would never come to the table if Ukraine joins NATO. They don’t have the military, troops, or money to benefit NATO, so the only thing Ukraine brings to the table is to poke Russia in their eye. Don’t let your dislike of Russia lead to support of a corrupt country that is only detrimental to the U.S.
