What France Did, See NATO

NATO has to accept a collective form of control over its armed forces. That means your army, your armed forces and their assets are no longer really yours. And if you are a nuclear power like the UK in France, then there is a demand that you will integrate your nuclear deterrent with that of NATO. So once again, your nukes don't really belong to you. They belong to NATO and you will integration your deterrent with thatof the other North Atlantic powers. That's again, loss of sovereignty.
