This is easily faked. Hezbollah probably has captured Israeli arms. The Hezbollah organization is an ally of the Assad regime, and they can use these weapons to make it look as if the opposition is in league with the Zionists.
Now, if Israel really wanted to help the insurgents (and there is little sign that they do), they could easily give them arms without Hebrew markings, and they would probably give them old stuff previously captured from other Arabs.
All we know is that the whole Arab world is in a great mess. If Obama ever had a coherent policy in the area, it is a shambles now.
Of course it’s faked. This is yet another piece of pro-Assad agitprop, which admittedly is commonplace, even on FR.
Yes, of course it’s fake, it’s pro-Assad agitprop.
