I thank the hon. Gentleman for that intervention, because it gives me the opportunity to expose some of the holes in his defence knowledge. The Royal Navy regularly bases a capital ship around the Falklands when the needs demand it, and there is also an offshore patrol vessel down there.
We have heard in today’s debate that nuclear weapons do not deter Daesh, but a battle tank will not deal with a cyber threat and an infantryman will not shoot down a high-altitude jet aircraft. The reality is that we need to consider the spread of current threats and possible future threats and then look at what we put into them. Could we, as a NATO member, realistically face nuclear blackmail? Yes we could. Vladimir Putin is not revamping Russia’s nuclear capability because he wants it to appear at an air show.
