That this was done by the Ukrainian “separatists” (in quotes because, as some commentators are beginning to recognize, these…people…aren’t interested in separation from Ukraine so much as they are interested in uniting with Russia) with Russian SAM systems and personnel assistance is by now quite clear.

The greatest foreign-policy failing of this Presidency is that he refuses to see that the world has bad actors. He can explain the consequences of aggression as he did on Friday, but he refuses to admit or explain that certain countries are responsible for those consequences and must be opposed.

Ronald Reagan didn’t flinch this way, and neither does Mr Obama’s own UN Ambassador.

Barack Obama, though, is no Ronald Reagan.
