Rosevidney, totally agree! Who are our Trident missiles targeted at these days ? I assume the Russians, because there's no other, obvious, target of national proportions. So, why have them? The cost of replacement would go a long way to procuring some very useful kit for the low level, religion based skirmishes we seem to be destined to fight for decades to come. No doubt, tactical nukes hold their validity, the trident deterrent has little or no effect on the religious zealot who believes it his duty to die for his God, believing in an afterlife full of virgins etc. Of course, having a nuclear deterrent gives us a seat at the table at the UN, and allows politicians like Cameron to big himself up on the world stage. It would be nice to think his military advisors are telling him, to spend the money more wisely.
