I heard on ABC last night that it was an iranian supplied UAV.
Confirmed apparently by the BBC and forensics from Israeli sources, so the question is, should the Israelis take out the Iranian faclity providing these tools, and likewise, should Hezbollah, take out the US production facility providing the ordenance that the Israelis use ?
We have to be fair, and we have to be seen to be fair.
Perceptions count.
