India do have decades long strategic relationship with Russia and India depends on Russia for almost 60% of it's defense supplies. This is, to a large extent, a legacy of the cold war as India was closely allied with the erstwhile Soviet Union while arch enemy Pakistan was allied with the US. India has been trying to diversify it's defense imports, increasing it's arms purchase with countries like US, Israel and France, with an aim of reducing its dependence on Russia. But the depth of Indian military ties with Russia is at a different level, it is inconceivable that any other country will be able to offer anything similar to it. The Russian help in Indian aircraft carriers, nuclear sub marines and Brahmos cruise missiles are perfect examples of sharing of advanced military technologies that any Western country may not be willing to offer to India. Russia has also hugely helped the development of Indian space program. It is perfectly understandable why India would not want to take a stand against Russia in UN forums.

There is also a case for historical gratitude. In 1971, during Bangladeshi independence war, the naval forces of US and UK had threatened India and at that critical juncture, it was the intervention of Soviet submarines that neutralized the threat.

The military and past relationship are not the only reason why India would take a neutral stand. Obviously a large powerful country attacking smaller country in whatever situation is a concern for all nations including India. But India and most Indians who follows International politics understand that Western countries have done the same in many occasions in the past decades. The second Iraqi war, Intervention in Libya and the former Yugoslavia are cases in point.
