A Contradiction?

Is this a contradiction? An element in our country believes the U.S. should leave Iraq, slowly or otherwise, so that Iraquis will take charge of their situation and deal with their problems. However, that same element doesn’t believe the U.S. should stop the flood of illegal immigration from Mexico so that Mexicans will take charge of their situation and deal with their problems. I’ve never been persuaded by do-what-I say, not-what-I-do policymakers, or those who invoke principles for convenience.
