#4 is where I would stop, to be honest.
1. A complete withdrawal from NATO is not in the cards at the moment. Putin would immediately act to put the Soviet band back together. It would be bloody in the Baltics.
2. Removal of troops from the Pacific would encourage China to take Taiwan, and it won't stop there. Taiwan is extremely important for the US, which is an unfortunate threat to our national security. South Korea is the same.
3. I don't know how you go about cutting the budget. There are already issues with the forces getting smaller. Gen Z is not buying in.
5. I'd pull back on the funding. And yes, tell them to move it to Geneva. The UN building can be a home for migrants that way.
1) fail to see the evidence for this. Putin has been in power in Russia for 25 years, and his wars with Georgia and Ukraine were in
large part fueled by US expansion of NATO and other various US shenanigans (CIA backed coup of a democratically elected gov't in Ukraine in 2014). Eastern Europe is of no concern to vital US global strategic interests or US national security. Zero. Zilch. Nada. The continual proxy war, sanctioning, and aggressive posture with Russia actually hurts US global strategic interests and US national security- as it's just driving the Russians deeper into the hands of China, which is a disaster scenario for the US longterm- which has always been worst case scenario for continual global hegemony of US- China & Russia aligning in an unholy military and economic alliance.
2) US will never remove troops from the Pacific. China is the only peer competitor in the world to the US, and the South China Sea is arguably the most important region to the US in terms of it's global economic strategic interests (Middle East right up there as well) and about a quarter of world trade flows through that region and 90%+ of advanced high-end microchips are manufactured in Taiwan. That much world trade flowing through there + chips our entire society, economy, and way of life are built around flowing through there = we are pretty screwed if that gets disrupted in anyway.
3) it's not that hard to cut the military budget, close down a bunch of bases (hint: we don't need over 800 bases in 100 countries) and start cracking down on waste and out-right fraud in the Pentagon. Pentagon has never passed an independent audit and has $2 trillion worth of assets it can't account for. It's the only government agency that has failed to do so. You can actually prosecute fraud and waste or just pass budget cuts to the defense budget- but our weasel politicians do not have the stomach for any of that.
4) UN has many flaws and issues- (permanent security council veto)- but it is an important world body that has largely worked in keeping another world war from blasting off since it's creation in 1945. I'd say we should probably keep it intact.
