Net win for India.

Their military cooperation with Russia provided numerous technology transfers which has benefited Indian industry and military arms sector.

For example India has its Brahmos / Brahmos 2 / NG cruise missile. They’re developing a hypersonic cruise missile with 1000km range with help from Russia.

I doubt US would give tech transfers of its older Tomahawk cruise missiles yet alone its newer stuff.

There are benefits to being neutral and purchasing from different sides.
