“Any great power that spends more on interest payments on its debts than on defense will very soon cease to be great,”

Total bullshit given the context of MMT and the accompanying willingness to spend anything (far in excess of any other country) on the military.

Be careful speaking out of school, kids.

unlike the first Cold War and the war on terror, the United States does not want to send its soldiers anywhere

Now this is a worthwhile observation, but a very superficial one. Some of the biggest "successes" for the U.S. in the Cold War came where troops were not ultimately needed -- we just helped install a dictator and then gave them assistance and political cover while they murdered all their left wingers. Besides, Vietnam and Korea (as well as Iraq and Afghanistan) can hardly be viewed as wins themselves.
