"Cobb-Smith has joined with the most politicized anti-Israel NGOs in pushing false or unsubstantiated accusations of Israeli violations of the laws of war […] In particular, he circulated false claims (“there was no tactical reason; there was no reasonable use of that weapon system”) as well as claims (later discredited) that the IDF used white phosphorous “in an illegal manner.” Similarly, he has been involved with the campaigns of the anti-Israel NGO known as Forensic Architecture.

Oh okey, I understand better what you mean by “not much to back those claims”
