It's only hypocrisy if you assume the US is a monolith. Most us citizens don't want a war and don't want to do anything to Greenland and think this is insane. There's some in favor of it because they own oil companies or are brainwashed psychopaths. Those are two very different groups of people and saying that the people who feel shitty about the actions of the psychos are hypocrites is rubbing salt into the wound when they are trying to express sympathy
