It's interesting that we've been told by right wing Conservatives and UKIPers about how the UK could become like Switzerland if it left the EU, with Switzerland being this bastion of prosperity and the free world, but when Corbyn talks about things like not having Trident or being part of NATO collective security we get this mass panic about how it would leave the UK defenceless and isolated.
Switzerland seems to manage fine outside NATO and without wasting taxpayers money on nuclear defences, perhaps without blowing money on overseas conflicts and unnecessary defence spending that's how they are able to keep taxes low and maintain a good investment environment.
Within NATO, Erdogan can be provocative towards Putin knowing that British lives will be able to be sacrificed to fight for Turkey.
