In the war between Russia and the Ukraine, Russia will win. However, in the event US or other NATO forces join in on an official basis, I cannot say what will happen. The strength of the US military has degraded in the last decade, and I do not know how much.

Do you think Russia will take over Ukraine after Russia wins the war?

I certainly don't think China can invade Taiwan and secure the economic assets Taiwan possesses, because the chip foundries are rigged to blow in the event they are seized by military forces. Because of that, China is strongly deterred from assaulting Taiwan. China is utterly dependent on chips Taiwan produces for it's manufacturing industry, and it cannot seize those foundries by force and get chips, so it's only option to maintain it's industrial production is to buy chips from Taiwan.

I agree with you!
I think China will use Taiwan hostage to demand more semiconductors and production technology from the United States!

Thank you for kind answer!😄
I hope your health and long life!
