You fell into the trap of lazing thinking promoted by the left. For example in 2022 the US had never record revenue with budget deficit of 1.4 trillion (FY-2022). The fact is the Democrats have built a government that we can't afford.
Why should we care about NATO? NATO exists to protect Europe from the USSR, which no longer exists. Plus, the lazy people of Europe are not doing enough to defend themselves.
First off. NATO was created to defend the nations of NATO against Russia. Ukraine is not a member of NATO. Russia is dug in like a tick in Ukraine. It will require a massive military intervention to change this fact. Are you willing to fight?
