President Obama's long-planned trip to Asia represented a chance to make progress on foreign policy even as Republicans stymied his plans at home.

In the end, domestic politics trumped all.

The White House canceled the entire trip late Thursday night, concluding it could not go ahead with even a curtailed five-day visit to Indonesia and Brunei during a partial government shutdown. And in doing so, Obama may have reinforced the perception that the U.S. may be incapable of following through on its overseas commitments.
