US earns a lot of money, and can afford a huge debt, by being a global superpower. By projecting power abroad, it also projects support for American businesses on worldwide markets. This is how the US earns enough money for a huge military budget, used to project the power. And all of this becomes possible thanks to alliance with European and other countries.

Current Russian invasion in Europe is about vital US interests. Support to Ukraine requires a rather small fraction of the US military budget. Failure in Ukraine will cost much, much more - probably including the American lives.

Thank you, brother, for your friendly shoulder. Your support enables us to stand firm.
