1. Obviously the Trump admin is requesting an increased military budget because of looming global conflict. We don't want to get caught with our pants down.

Russia obviously bears the moral blame for starting this war, but Putin clearly was tempted by Western weakness. Had European states kept large and effective militaries and credibly threatened to employ them in Ukraine's defense, we probably wouldn't be where we are right now. So in some not insignificant measure, historical European underspending has contributed to the need right now for dramatically increased spending across the entire alliance.

2. I disagree with GP and agree with your cynicism there. US domestic policy failures are in no way caused by foreign intransigence of any kind. IIRC we spend more on health care per capita than (almost?) any other nation yet rank nowhere near the top in health outcomes. That's on us.

And I think it's important to correctly identify the root cause of our broken domestic policies, because I suspect fixing that issue will fix more governance failures than just healthcare.
