When Germany starts acting like they actually believe Russia might expand past UKR and fight NATO countries, and is willing to commit serious money to that problem, that's when you've got my interest. However the current situation is that we're rushing to rescue Western Europe who doesn't feel threatened or inclined to break the bank investing militarily due to ann imminent Russian invasion. At the same time we have ever more serious domestic issues. The reply always seems to be "it's not either or, we can secure our border and the borders of Ukraine" except we can't, or we already would have.
No love for Russia here, but I 100% believe our over-investment in Ukraine is strategically foolish. CH, I get your point on pre-WW2 isolationists, but I am unconvinced Russia is analogous to Nazi Germany and Imperial Japan. It looks like a regional dispute to me. And instead of engaging in thoughtful discussion to convince me, the prevailing approach is to bully me by claiming I'm parroting Putin talking points like a stooge. If Covid has taught us anything, it's that people yelling thoughtless demands and name-calling must be ignored.
