Which missiles are coming from the US, UK, Australia, New Zealand or the other Anglo-sphere countries?
True, but you put your trust in missiles like this:
Now I'm not suggesting India and Israel spit anytime soon, but if the future can't be known, why trust an Israeli system either? Or Russian? Isn't the possibility of a beef between India and Israel possible given India's ties with Iran and Israeli opposition? Wouldn't Spyder constitute the same risk given Israel's known cyber capabilities and penchant for self-preservation above all else? There's definitely a greater risk to India from the US then Israel, know doubt, the same risks are still there if "We never know the future".
FYI, Norway, whom is the developer of this missile system India is interested in (or speculated to have purchased depending on your sources), isn't an Anglo-Saxon country. Few in Europe or the Americas are. Just the Anglo-Sphere, which ironically, includes India to an extent as well.
