To be fair (to the western govts) when was the last time nuclear weapons were used?
With the amount of planning and analysis required (not to mention the expence) with precision weapons, I think that the western powers are trying pretty damn hard to avoid civilian and collateral damage.
why dont we unload the royal navys entire stock of tridents on france to test this theory that it is unlawful if it is proven to be unlawful well we will have got rid of france so we would have to pay the compensation to a small pacific island that the frogs had flatened with a nuc its a win win situation
I am afraid that politically to become a non nuclear power would be stupid, out permanent seat on the UN Security council is in part atrributable to the fact we are a nuclear power. It ratehr depends on the point of its use. If it is a deterrent against attack on the UK mainland then I would suggest that if these weapons were to be used it is likley to be as a result of an equally indescriminate attack on the UK. If we have nuclear weapons for use against aggressor nations that are not themselves nuclear then I would agree, we would clearly be illegal. However if we reach the point of using them I doubt that we will care about the International Court of Justice.
