But, that's the real issue; the US military is not being used as an agent for global peace or to protect its borders, but for imperial hegemonic domination.
The founding fathers were weary being drawn in wars that do not serve the nation's interest. Washington and Eisenhower both were against wars whose purpose were outside of direct invasion. Such wars and the garrisoning of the planet by the US today is fiscally unsustainable and actually is a major cause of the social inequities and infrastructure degredation that have allowed the Democrats to pursue their socialistic agenda today.
Yet, nothing you said negates what I said. Regardless of the results, the fact remains that a strong military is a Constitutionally mandated function of the Federal gov't. HOW that military is employed will always be debatable.
Isolationism doesn't work. We tried to follow that doctrine until Japan attacked. Like it or not, we have interests around the globe, and some of those interests are because we have alliances.
We have the size military we have, not to be imperialistic, but because Russia and China have been real threats for more than half a century. as they grew their military strength, we also needed to grow ours.
It's difficult to argue reducing our military strength when history proves the guy on top of the hill is always going to be challenged. We are, and need to stay, on top.
