Yup, the international community has already accepted India’s version (I say VERSION because I know you are all still in denial) that there was definite Pakistani involvement. It is possible results of investigations (proofs reports whtvr) were shared internationally or with Pakistan to convince them that "See i told you, there is a link ". I wouldn’t be surprised if they don’t want to reveal everything in the media because it might hamper counter terrorism efforts in the future?
Your mentioned claims were already accepted as excuses and lies by Indians and other international intelligence agencies. Now you’ve confirmed that these were indeed lies.
