Aside from Ukraine & Afghanistan war(and this one is for US self), what wars have been fought because the US intervened due to threats against NATO members?

See https://en.wikipedia.org/wiki/2011_military_intervention_in_... -- initiated by France and Britain, proving that NATO is not a "defensive military alliance"

https://en.wikipedia.org/wiki/NATO_bombing_of_Yugoslavia -- another offensive "humanitarian" action

By withdrawing from NATO and pulling our military bases out of Europe, it becomes more difficult for the US to "intervene" in the Middle East at the pleasure of Middle Eastern interests.

Furthermore, if Russia invades more countries in Europe, I don't want the US to "intervene" with yet another "humanitarian" operation.

We can slash the size of our military and spend that money at home on healthcare, debt reduction, etc.
