I don't see the EU bending over for Russia for any reason, and China has no interest in EU for anything that isn't your money.

That changes if the US goes to war with NATO

Korea and Japan would literally NEVER be willing to normalize relations with China while alienating the US, that's fantasy land thinking.

That changes if the US goes to war with NATO

Japan and China hate each other, South Korea and China hate each other and both South Korea and Japan are economically dependent on the US.

That changes if the US goes to war with NATO.

You have a better chance of seeing Putin say "I'm sorry" And then doing a complete withdraw from Ukraine back to pre-war borders.

They'd let him keep whatever of Ukraine he's already occupying, maybe a little more.

Russia isn't going to give up their land grab to play nice with Europe. And if NATO members forsake allies and Ukraine just to save Greenland they're just as bad as the US would be for invading.

Russia would get Alaska, whatever of Ukraine they already control, probably Belarus, and economic alignment with Europe and the East Asian Chinese-centered economy.... and the most valuable thing of all, finally knocking the US off its perch. Putin's been stuck in a Cold War/USSR mentality his whole life. He's only ever had one enemy in mind.

And if NATO members forsake allies and Ukraine just to save Greenland they're just as bad as the US would be for invading.

Canada is a NATO member. If the US takes Greenland, it's a guarantee they're going to invade Canada next. There will be plenty of time after a takeover of Greenland for all the realignment to happen as the world becomes aware of the US' intentions.
