Former Senator Phil Gramm used to have what he called the "Dickie Flatt" test: he would ask himself if a certain government expenditure was worth taking a dollar from his friend's wallet. I don't think anybody in the Obama White House has any clue or compunction about where the money comes from: "U.S. ready to join $100 billion climate aid fund."
Sure, why not? Throw it on the pile.
