We tend to forget the cold civil war against Muslims that has been real war in the past resulting in the creation of Bangladesh. So for India, helping Palestine also means giving a friendly signal to Iran and Russia and its Muslim neighbours.

They may not have heard about the Emirates making friends with Israel - or simply Iran is closer and more dangerous especially as it joined the Russian Chinese axis.
