Even with reshoring, it's not as though China would just shrug and give up Tibet, and a military confrontation with them over Tibet would be profoundly unpopular in any reasonably foreseeable political landscape. There is no underlying racial animus to drive focus on the issue, as there is with conflicts in the Middle East. For most Americans Tibet is a place they've never been, know precious little about, and while they may feel badly when the situation is explained, it isn't going to weigh heavily on them. It would be hard to explain why that's something to be prioritized over the MENA region, Russia and Ukraine, or places like Mali, Niger, and Sudan.
Is it just due to numbers? Middle East conflict has Muslims all over the world engaging and amplifying the issue. But there are few Tibetans and no allies of theirs to really speak of in the same way (as with the international Muslim community).
