Sounding more and more like a Wall Street economist, it appears US intelligence has made up its mind that pro-Russian separatists shot down the Malaysian Airlines jet in Ukraine... but are not really sure... As WSJ reports, a U.S. official said there are “indicators” that Russian separatists fired the (BUK) SA-11 that took down the plane, but that officials have not reached a definitive conclusion. "There are still a lot of questions," the official said. So - put another way - they have no idea (but know what they would like the answer to be).

As WSJ reports,

The U.S. now believes that pro-Russian separatists were responsible for firing the missile that downed a Malaysia Airlines jetliner, a Defense official said Friday.

Officials in Washington also confirmed that the missile was fired from a Russian-made SA-11, or Buk, system, the Defense official said.

The official cautioned on both findings that a U.S. probe isn’t complete and investigators and analysts are still sifting the circumstances surrounding and leading up to the firing of the missile.

Another U.S. official said there are “indicators” that Russian separatists fired the SA-11 that took down the plane, but that officials have not reached a definitive conclusion.

“There are still a lot of questions,” the official said.

The U.S. official said the missile was fired from “the border region” but declined to give a more precise location.
