You mean why do we need Greenland and Canada?

US power in Europe has been our intentional policy since the end of WW2. I can't do justice in educating you on the geopolitics of it all but there is a plethora of information out there for you. Not sure how an American can get to be an adult without understanding the background and reasoning.

We did this to the point of encouraging Germany to include limitations on their own power in their constitution (along with Japan). Anyways it's a long, thought out standing position of our country that has 70 years of thought put into it versus the recent 'but it's not fair to us' MAGA reaction based position.

Because the alternative to a US dominated world is a world dominated by someone else.

History has shown that lesson again and again and again. There is no “peaceful world without a hegemon” period of history. There is Pax Brittanica, Pax Romana and Pax Americana which is now coming to an end.

You asked this exact question last week and I answered it. If you are just going to ignore the people who reply to you, why bother commenting?

So we can extract value value from having the biggest stick. Surely any competent businessman turned president couldn't fail to turn a profit when our military, and only our military, can secure the safe travel of goods anywhere in the world and overthrow any non-nuclear power who acts not in america's interest.

Same reason US needs a huge military.

Deterrence and overwhelming force are the only ways to ensure longterm peace and stability.

That's about two orders of magnitude more thinking than they're actually doing.

It's not the point for the MAGA types. They want the power AND deference of the good old days, not actual feeble pullback and irrelevance. They think Europe paying it's share means Europe will pay for OUR military presence. Add on their kids no longer having access to military jobs/path to education and those communities will start to freak out. Trump wants to project power in the middle east. That's current done out of European bases.

tell that to Greenland.
