Every old nation has territories which would be hard to claim if not for historical reasons. To take my own country as an example, the justification for France to own Guyane, Guadeloupe, reunion island, etc... is slim at best (France just happened to be a former colonial power).
As for your points 1 and 2, do you think people don't attribute those to the US as well ? Point 1 in particular falls into what is called unilateralism - a pervasive notion in the political discourse of the US since their inception. My point is not to fall into superficial anti americanism: it i simply in the best interest of the US to act this way, and most countries pushing for multilaterilsm are countries without the power to act differently anymore. But moral, fairness has absolutely nothing to do with it.
