It seems that Israel launched a major attack attack on installations around Damascus last night. It would be the second Israeli attack this week. There’s no confirmation yet, but not many actors in the region have the hardware to do this sort of thing –
You’d think Assad would normally respond, but he’s fully engaged in a war as it is. Presumably he doesn’t have spare forces to send over the Golan Heights. And what does Israel gain by aiding thousands of allahu akbars? There are plenty of insurgents fighting to take over Syria who would not make great neighbours for Israel.
