The Hinduism has a lot common with Judaism, both religions are ethnic religions, Jews like Brahmins call themselves God's chosen people and other people related to other religions as gentiles (non humans), The followers of both Hinduism & Judaism are extremist to the core, the fascists, consider butchery against other religions a good deed and their right at the same time.
Both have captured territories of other nations, that does not belong to them, Palestine and Kashmir.
Both are using hard, cruel state power against the un armed people in order to suppress their right of self determination.
Both are barbaric against minorities, i.e cold blooded killings of Palestinian civilians by Israeli people and security forces, and communal violence along with daily lynching of minorities especially muslims by extremist hindus, planned and executed by Indian state governments for political gains.
So its a natural alliance as far as Hindus and jews are concerned, in fact the leaders of both the nations admit that publicly, so its natural for both, to cover/defend each other's racism & brutalities.
