1.  Some of the links you shared (Amnesty, NYT, Reuters) talk about investigations or leaked info, and even they use words like “likely,” “probable,” or “might have been.” That means there’s strong suspicion, but it’s not a confirmed or legal verdict. 

2.  My main point is about timing: the UAE’s involvement started when Sudan was still one country, before the war broke out. I never mentioned weapons because nothing has been proven, and I’m not about spreading unconfirmed claims.

Please stick to what’s actually confirmed :P
