Israel's defence cooperation is not against Pakistan, but for the mutual beneficial of both sides. Russia helped India in empowering its military power more than Israel will ever can, does Russia is an enemy of Pakistan? Last time I checked there was a Pakistani embassy in Moscow, perhaps even with a military attache.
Pakistan has military cooperation with many countries in the Middle East, is it against Israel or in favour of Pakistan's defence industries? Same applies to Israel-India cooperation, no need to involve any nonsense about Zionist-Hindo nexus.
