There was a particularly memorable use of this sense some time ago, when the UK representative to the UN explained that they abstained from a vote in the General Council that passed with something like 200+ members voting for it because "the international community is still divided on the topic".

That's because you're reasonable.

Sometimes it's used in the expected way, but (more?) often, "international community" euphemistically refers to whomever is currently one of, or an ally of the above mentioned countries.

China, Russia, India, Pakistan, Iran, Saudi Arabia, and many many other countries that are very active members of the international community are not counted among members of THE "international community". Hell, much of Europe isn't either, including some of the former colonial empires, on some topics.
