Ah well: while there is a general tendence in the USA to buy everything the Israelis claim (then 'Israelis know everything better, they are our friends, and they never lie...' ...cough, cough...), I would say it's at least 'worth considering' that there are alternative ideas in regards of culprits for such attacks.

One of these is that it's the IRGC that's staging such attacks.

Reason?

Provoking Russians, spoiling negotiations etc.

If so, these attacks were highly successful: the VKS is meanwhile back to bombing the crap out of insurgent-controlled Idlib.
