Etymology Of "Like A Developed Nation"

Recently the block of developed nations at Copenhagen have undermined the Kyoto Protocol. The Kyoto Protocol states that the industrialized nations have a historic responsibility as they solely contributed to global warming in the past. Hence they should be the ones undertaking the most reduction in green house gases and should also help the developing nations financially and through transfer of technology to reduce emissions. After they effectively shrugged off this responsibility at Copenhagen,what better way to poke fun at them than to coin a new term for irresponsible people?

Thus the phrase "like a developed nation" is born. It means not owning up to a mistake committed in the past, and trying to pass on the blame to the person/party who is the victim.

Examples of usage are as follows:
-Girlfriend to boyfriend,"Don't act like a developed nation by saying that I was the one who seduced you."
-Pakistan is acting like a developed nation by claiming Indian influence in Balochistan resulted in the civil war.
-The professor behaved like a developed nation by blaming the students for their lack of knowledge.
