I think he's an immature person who acted in a fit of pique. I think it's all about him and attention seeking, and has very little to do with what is "right" for anyone other than himself. IOW, a narcissist rather than a person of principle. If it were about principle, he wouldn't be in Russia (thereby implicitly conveying the message that Russia is better than the U.S.), a country which imprisoned a girl band for criticizing the government (not publicizing classified information which he had agreed to keep secret), and which has most recently taken to flogging that same girl band with a horsewhip.
Really, am I the only person on this board who sees the laughable absurdity of this?!
