While we are deploying troops in their thousands, we lose the chance to build up their basic skills.
There are some days when history is made. Yesterday was one - and I was honoured to be in Washington to watch Barack Obama being sworn in. During his soaring inaugural address, the new president gazed over a teeming National Mall that was crowded with more than a million people.
Whatever he does in office, no man can live up to the high expectations of the world, but we have been changed by his election. Obama's inauguration is a historic global achievement, a major milestone in the journey of a powerful nation.
I agree with the British Legion that we have a responsibility to support our troops and support their families, particularly when we are asking people to do very difficult and dangerous things for our security.
