This has less to do with the MIC, and more to do with America attempting to consolidate its spheres of influence. Trump doesn't want isolationism, he wants to strengthen certain areas of American influence, and abandon more overstretched areas(Eastern Europe and the Middle East), in a coming war against China.Wars for the sake of wars. I guess you gotta feed the defense industries by finding scapegoats and imaginary foes. As they say in the law of the jungle, the empire got to maul the weaklings to stay afloat.
By that logic someone somewhere will outmuscle you one day. The law of nature, what goes around comes around!
