This is why Corbyn will never be PM, not because of his policies but his lack of communication skills. Emily Thornberry was just as bad on Sunday Politics. One of the options the Labour defence review will actually look at it is the 'Japenese' model whereby the delivery system is maintained but the warheads are removed and dismantled. Should circumstances change the warheads can be assembled and the delivery system is in place. Contrary to what Andrew Neil said the missiles will not be armed with conventional warheads both the missiles and submarines would be placed in care and maintenance.
I'm not convinced myself but it would be good to actually hear the arguments instead of incoherent ramblings by the Labour party.
