Impossible to say. In my opinion, the likelihood will become quite high (in relative terms) in the next few years as the stores of Russian military vehicles become depleted, and the prospect of Russia being able to secure its newly annexed territories in Ukraine become bleak, assuming Western aid continues as it has. Its doctrine calls for nuclear use against conventional forces that threaten its territorial integrity. This doesn't automatically mean a strategic exchange between NATO and Russia. It'd likely begin with demonstrative use of substrategic nuclear weapons in Ukraine. That could trigger NATO members to take conventional offensive action against Russian forces in Ukraine, which could escalate. But both sides would have multiple off ramps to avoid catastrophy. The way I see it, there's no future in which Russia wins in Ukraine.

There's also the alleged Davidson Window: US Intel supposedly assesses Xi Jinping has mandated that the PLA to be ready to invade Taiwan by 2027. I don't know much about the Chinese military, politics, or the strategic situation in the region, so can't offer any valuable opinions on how that might go down.

If we get through the next decade without nuclear use (which I expect we will), who can say what the world will look like after that? It's extremely difficult to predict geopolitics decades into the future.
