I'm a tad baffled by the criticisms of Jeremy Corbyn for confirming the bleedin' obvious - that there is no way that he, as a lifelong unilateralist, would ever push the nuclear button and mass-murder millions of innocent men, women and children in foreign lands. The argument seems to be that he must submit to the collective will of the Labour party, which at present is pro-Trident, thus requiring the maintenance of the fiction that British nuclear weapons might one day be used, in order to make the 'deterrent' effect credible. But the decision to launch a nuclear attack is not, and can never be, a decision by committee. It won't be remitted back to the Labour conference, and then resolved by a tortuous GMB/Unite composite motion. It's at the total discretion of the Prime Minister, and Labour members have effectively delegated that role to Corbyn, subject to a general election victory. If they wanted a leader who was willing to push the button, they should have voted for someone else. Nobody was pulling the wool over their eyes.
In any case, it isn't actually true (unfortunately) that Corbyn's refusal to use Trident renders Labour's support for it redundant. Even his most fervent admirers don't expect him to be Prime Minister for more than a few years, which leaves plenty of time for a bloodthirsty Labour PM to succeed him and get back to the serious business of destroying humanity. The only thing the 'moderates' have to do in the meantime is stop disarmament taking place, which in Yookay Okay ought to be an absolute doddle. So please stop worrying.
