To maintain its world power, the US has built a Wall of Enmity between the East and the West. With the fall of the USSR, the Wall was not abandoned but extended into the Russian territories of the former Soviet Union. The Baltic Republics are firm members of the Wall, despite the fact that they are in firm super depression because of severe Russophobia. Poland, Hungary, Romania, Bulgaria, Czechia, Slovakia, and the new republics of former Yugoslavia: Croatia, Slovenia, Monte Negro. Serbia, so far, have refused to join NATO. Promises not to expand NATO were made by the US to Russia. Apparently, promises were broken. In Europe, NATO is shaking but not breaking down; it is the Key Stone of the Wall of Enmity.
In the Middle East, the Wall of Enmity is breaking down. Turkey, a key NATO member, is confronting the US on all fronts: Jerusalem, Palestine, Syria, Iraq, and Iran. Turkey has not forgotten the failed coup attempt of July, 2016. Turkey is suspicious of the US. The US is treading gently because Turkey is the main fresh water supplier to Israel. The US does not want to lose Turkey as it lost Iran.
In South Asia, Pakistan is definitely drifting away from the Wall of Enmity. Trade with its key partner, China, is in Yuan. Intelligence is no longer shared with the US and it may block US access to Afghanistan. The US is trying to woo India but India is very fickle; it is not likely that India would join the Wall of Enmity.
In South East Asia and Oceania, only distant Australia, New Zealand, and some island states of Oceania are firm members of the Wall of Enmity. All littoral states of South East Asia do not want to antagonize China.
The North East Asia Wall of Enmity is pivotal to US power in Asia and the Far East. Under no circumstances is the US willing to lose it. The only way to maintain its position in North East Asia is by stoking tensions with North Korea. South Korea under President Moon is trying to eliminate confrontations with North Korea. The Winter Olympic Games are possibly a blessing in disguise. No war during the Olympic Games was an ancient Greek tradition. Talks between the Koreas that will exclude the US may lead to something significant which the US will not like. Bluntly speaking, South Korea may refuse to be subservient to the US.
If South Korea refuses to be subservient to the US, will Japan be far behind? Not likely.
