The Israeli bombing of a site in Syria is still more than a little mysterious, and all the governments involved (including the U.S.) are working -- with different motives -- to keep it mysterious. Here's a piece by former CIA officer Philip Giraldi that presents the best case I've seen that it had the nature of a disinformation operation by Israel -- done to create the impression that Syria had a nuclear enrichment program provided by or in cooperation with North Korea, or the beginnings of one, even though "North Korea isn't known to have ever exported nuclear technology or material. The prevailing consensus is that Syria doesn't have the economic or technical base that would enable it to develop a nuclear weapon even if someone handed it the fissile material." There's also the question of whether what North Korea exploded was really a battlefield-ready nuke or a primitive thing that only worked partially. Plus, as Giraldi points out, no evidence of radioactive material has been found in the wake of the strike.
