China has been threatening to invade Taiwan for years now. Not to mention their, at best, dubious claim of the South China Seas through use of naval force for the 9 Dash Line against other nations in the area.
Is invasion the only grounds for moral authority? Does one only need not invade a country to claim it?
And are you claiming that the US sends humanitarian workers, who are actually soldiers, to kill children in other nations?
Probably for the best, honestly. I can't bring myself to block people like that, though, because it helps stay on top of the rhetoric being thrown around.
