Maybe from a humanitarian position, but the U.S. government shouldn't be a global humanitarian project. If we are, we are pretty terrible at it. The U.S. government ought to be dedicated to benefiting U.S. citizens first and foremost. I don't think those who are opposed to this are genuinely opposed to it on humanitarian grounds either. They want to paint anyone who disagrees with them as racist or inhuamane while working on the behalf of corporations seeking cheap labor.
