Somewhat cynically it's entirely to do with which country they attacked. Had they moved on one farther away from mainland europe I doubt we'd have heard nearly as much about it.

That said it would still be wrong just as much of US (and yes Chinese) foreign policy is morally wrong. Such should be called out rather than engaging in whataboutism.
