The blast in Lebanon is changing the balance inside Lebanon. Will it be enough? Depends upon what is uncovered examining the blast and who had control of the explosives.
Not sure I believe the Ammonium Nitrate explanation. There was talk about rocket fuel. Judging the photos of the blast, might support that view. And it appears the majority of the blast was vertical. Yes, in spite of the blocking of the blast by the silos, which helped, the damage was huge. But it could have been much much worse had the full force been at ground level. It is unclear what triggered the 2nd blast. I've read some plausible scenario, but no clear explanations.
Looks like Egypt is seeing new link with Assad and Russia.Egypt could use Russian help if they move on Eastern Libya. They may be useful if Assad moves on Lebanon (as well as Egypt’s unoffical ally Israel). I believe a move on Libya would split that nation with the western half becoming a client state of Egypt and the oil money going to the Egyptians. If Egypt moves on the Nile dam—they will need all the help they can get from Russia (They could not count on the USA if Biden gets in power—and Obama is the real power).
