No, if the US considers it be a regional conflict, then that's all it will be in terms of repercussions or interests. Maybe in terms of vague geopolitical concerns that might be relevant decades from now, though even that is unclear, but the US is too powerful to have repercussions from not being involved in this conflict.
China and other countries don’t see it that way. They are looking for signals as to what they might be able to get away with, now that the US has decided that it chose the wrong team during the Cold War.
If China seizes Taiwan, we're going to do exactly squat about it. The best thing the USA can do in regard to that situation is stay quiet, and let the status remain unchanged without goading China into doing something to save face.
And that means no more moronic field trips by grandstanding senators.
China would have seized it already if they were sure there’d be no US response. But if the US continues to wink at Putin’s crimes, they may change their mind.
You’re misapprehending the logic of the discussion. OP suggests that this is a regional conflict without implications for US interests (see their response to my comment if you think my interpretation is off). I said, “Really?” My questioning that claim doesn’t imply any commitment to the claim that the US must intervene in all conflicts that have implications for US interests.
