A Labour MP is about to resign over Tony Blair's desire to update Britain's nuclear defence systems. Good on him. Many more should do the same.
Those who change history are those who make themselves vulnerable.
If Britain truly wants a role on the world stage: if we want to influence for good, then we must go the way of Christ, Gandhi, King. We should abandon new plans, scrap the existing systems and kick out the US's systems too. Only then will we have any integrity to challenge Iran, North Korea and the USA.
