How to make a row about defence worse

There are many quite understandable reasons for not promising to protect the defence budget. Some are pragmatic: there’s not much room in Whitehall for more budgets to be protected once you take into account those that already are. Some are theoretical, including the argument Clare Short advanced on Newsnight yesterday, which is that if your economy grows, you have to spend more on defence in order to keep meeting the target of 2 per cent of GDP set by NATO, and that has nothing to do with whether you need to increase spending but with statistical releases from the ONS.

But whatever the good arguments, they aren’t being made nearly as often by ministers as the blunders and insults are flowing towards those who argue in favour of a 2 per cent target. First there was Philip Hammond’s line to Tory MPs that there are ‘no votes in defence’. That at least had the virtue of being close to the truth.
