The last several decades of loss of life and treasure in the neocon-neolib pursuit of leading and enforcing a world order is coming undone, as those commenting here sometimes thrown Putin-ist and Biden-ist pejoratives as if grenades. What may be known is that the EU has played the US as a patsy for decades, and NATO and the EU have both pursued expansionist goals as if immune from market forces. Withdraw a secured energy supply and we see the quick result. Ditto for the last year and a half which took a newly energy-independent US and made it a net importer of energy again.
Seems to me that the poles are not between nations as power blocs these days, but between governments and their hoped-for generations of serfs in the Hayekian sense, working to pay "perpetual debt." Certainly this is the message from the UN as from the WEF.
As individuals, we live in cooperative communities, it is true, but we also are each our own separate "pole" such that a multi-polar world should not hold the catastrophic vision some hold for it. A uni-polar world, on the other hand, can only be ruled, as in the dream of aristocratic and Marxist dictatorships.
That a Japan might plan for its own survival is what Japan should do. And every nation of the world as well. Is the US a "credible" defense partner? Certainly given the invasions and bombings and color revolutions in which the US has participated in the last several decades suggests we are a credible OFFENCE partner.
Given the likes of the J6 committee's offense of late, as one example among many, other nations would do well to consider such.
Your #7 is outstanding, and this comment in particular drives to why Trump was hamstrung with Russia-gate and the Ukraine impeachment. It's now apparent he stumbled into this global political slush fund and with that he endangered the principals involved. I've very interested in knowing if they offered to 'cut him in' on the deal, or did they just hope to take him out politically. But like Frankenstein, he's lives and he's headed back to their village. They'll be ready and so will we.
