You really need to study the history of WW2. When a tyrant has global aspirations and the USA decides to bet we're protected by the Atlantic Ocean, there is always blowback.
Most Americans if given a choice would avoid war at all costs. That's not the same as appeasement. Giving over Eastern Europe to avoid another war is not how you stop someone like Putin.
Ironically, we spend almost a TRILLION dollars annually on our military budget, but when actual global events demand that we act, conservatives are covering their eyes.
That's not how you defeat monsters like Putin.
