What has Cameron done in this and his previous term? Not a lot - except talk of course. Big promises made in opposition haven't materialised, and despite appearances, the fundamentals of our economy and NHS are on life support. He's going to do what most modern politicians do, which is talk and make popular promises. However, he won't want to do anything that will make waves, and by the time the plebs realise he's full of it, he'll be gone and we'll be onto the next one who will promise to be new, improved and washes whiter. Then it starts all over again, as The UK slides inexorably downwards.
What he and Osborne have done is significantly cut government spending, ensuring that the UK maintains a AAA credit status (which reduces the cost of government borrowing) and reducing the deficit, and created a strong economy that is seeing significant drops in unemployment. Osborne was widely criticised five years ago, with Balls and others saying his cuts would destroy the country. He had more balls than Balls, and held his own, so to speak, he had the courage to follow his plans.
And if doing something means invading Iraq, giving back some of the EU rebate, and hugely increasing public spending, I'll opt for not doing something thanks.
