If he could show he was sane, some of his positions, namely Nationalism, wouldn't be so awful. But he's a lunatic. One does have to consider that extracting from NATO, while treasonous to allies, would guarantee American lives being spared.

Historically, the US has been all posturing and no action in Russian aggression. They in and with NATO have abandoned several satellite countries with little more than sanctions and threats.

The real question is are you willing to see your American men and women go to WWIII for Ukraine. And with the hundreds of billions Ukraine has received, perhaps paying for them to be the shield is price enough.
