The really interesting thing about this whole fiasco is that despite all the naval redeployment, huge cost, inconvenience to the locals, and massive entourage, the purpose for the trip is really quite vague. I can't find much concrete on it that boils down to more than a sightseeing trip through Asia, with no particular reason for the three days in India at all other than to reassure them we aren't trying to poop on their heads while trying to be nice to China and Pakistan.
I think Hallmark sells cards for that kind of thing that run a lot less than a half-billion dollars. Of course we know from past Obama diplomatic triumphs (cough) that formal gifts to heads of state won't run up the bill very much.
