Thanks, Steven W.
As is frequently the case, you are waaayyyy ahead of the crowd.
This does make it seem quite likely that Israel used some rather advanced weaponry to cause the explosion, and that the primary target was Hezbollah—the global terrorist/drug-trafficking/human-trafficking organization protected by Obama ... possibly the conduit for his bribes received on behalf of Iran.
Fun Facts: The Beirut explosion was 10 times larger than a MOAB, the largest fuel air explosive in the US arsenal and equivalent of a 3.3 earthquake.
I’ve seen RUMINT un-sourced that MOS got a scientist in there. I like Wictor’s analysis - first the warheads blew up, the first half of the fuel was burned (brown smoke) and then the remainder blew up (generating the vector). Quite a sophisticated operation.
