>>5859>Are there any methods for defending your country from a nuclear strike?None whatsoever. Trying to intercept an ICBM moving 20 times the speed of sound is harder than shooting a bullet with a bullet, not to mention cluster munitions that split into multiple warheads. Both Reagan and Trump failed to understand this and the US government has squandered a lot of tax dollars on trying to solve this unsolvable problem, but the fact remains that intercepting a missile in flight will always be many orders of magnitude more difficult than launching one and any missile defense system can be overwhelmed by simply launching more missiles.
>could there be a way to neutralise the threat of nukes altogether?Sure, you just have to get every country in the world to agree to dismantle all of their nuclear weapons and never build them again.
>some sort of defence wherein the nukes are disabled before impact by neutralising the warhead with some sort of force field?No, nuclear warheads are heavily shielded and even an electromagnetic pulse from another nuclear warhead would not disable it. Shooting them down with lasers won't work either, due to atmospheric scattering.
