Re 2), I’m shifting on Ukraine. Used to support backing them 100%. Not so sure now. Too much corruption. Not our fight? But Ukraine is the backdoor to Europe. Also Putin is a monster. Add in though Ukraine’s historic anti-Israel stance. Then counter with Zekensky condemning Hamas and saying he stands with Israel. That one is too complicated for me to have a solid opinion. Just wish Europe would do more to handle it, but guess that’s a pipe dream.
The Ukraine is front door to Russia, a well-used path of invasion both from Russia and to Russia. There is no way that Russia can allow NATO to squat right along its border in the best spot to invade Russia.
