Some have wondered what the Obama Doctrine is. I believe Bryan Preston at Pajamas Tatler has found it. Obama made this statement in El Salvador:
And that’s why building this international coalition has been so important because it means that the United States is not bearing all the cost. It means that we have confidence that we are not going in alone, and it is our military that is being volunteered by others to carry out missions that are important not only to us, but are important internationally. And we will accomplish that in a relatively short period of time.
The Obama Doctrine restated in plain spoken clarity (which politicians never come near) is: America will not assert its national self-interest, but if other countries want to volunteer us to sacrifice for the rest of the world, we will be glad to serve.
