Earlier quoted context omitted.
USA will have to give a shit for one reason: the war against Baltics or Poland is the war against whole Europe. Germany will not stay away and observe, as will not do France or Italy. EU is the largest trade partner of USA, the biggest market for its exports etc. Regardless of the strategic games in the Pacific, USA cannot afford to lose it or to allow it to be devastated by a big war.
I am all for international trade. But can we let the European countries grow up and provide their own defense? USA can't really afford another decade of aggressive military meddling. Deficits are running away from any plausibly realistic plan to balance spending and tax receipts, so we are economically killing our future.
How about pay your fucking debt and keep Russia at bay.
