As Tom mentioned below, the topic of a recent air raid by Israel into Syria came up in last night’s Democratic debate. John Bolton does a much better job of describing the threat (no shocker there) than any of the Democrats. From the Jerusalem Post:

“What the Israelis struck I cannot say; whether a nuclear or missile facility is not clear,” Bolton said from his office at the American Enterprise Institute, a conservative think tank. He offered the possibility it was a joint research venture or simply a North Korea facility located in Syria. “Any of these options is enough to show proliferation by the North Koreans and that is very dangerous,” Bolton said. He ruled out other theories, meanwhile, including the target was Iranian missiles to be shipped to Hizbullah guerrillas in Lebanon for attacks on Israel or that Israel was testing Syria’s air defenses. “I don’t think the Israelis would have taken the risk unless it was a very high-value target,” Bolton said.

The Post included this informative graphic to show just how far Israel’s bombers had to fly to carry out the mission.
