there are talks to give [Saudi Arabia] nuclear weapons, so that they could defend themselves against a possible attack from Iran.
Please explain the application of nuclear weapons for defensive purposes, I have never heard of such a thing!
Are they putting their nukes onto superfast superaccurate space-missiles so they can use them to shoot down incoming enemy ICBM's from secret stealth satellites in low orbit?
Or is it a ground-based nuclear-fusion laser of some sort?
