While I lean pretty hard to the Isolationist front, this article is ridiculous in its oversimplicity and failure to recognize the reality control of the seas and manupulation of key markets plays in the day to day prosperity and success of “The Republic.”
Fool-hardy is taking an approach this simple.
We need a mix of fortress America, unquestioned rule of the free seas, and dominating air wherever we go.
However, this is all a non-starter as long as borders remain open and we continue importing every single dam vagabond from every single country in the world, especially Muslim ones, as a matter of deliberate and continually policy. You need to meddle and have control over the places these leeches come from if you are going to let them all live and move here willy-nilly. Otherwise you are inviting yourself for the worst Trojan virus/attack ever.
Get the borders sealed shut, stop LEGAL immigration, starting with banning Muslims first, then we can start talking about military projection abroad versus home.
There are certain squabbles we should never get involved in, Intra-Arab/Muslim being foremost...The more they kill each other off, the better.
