Let me try to find a little common ground with the hon. Gentleman. As well as believing in the importance of defence expenditure and keeping our defences strong, I also believe that international aid and development is an important tool not just for helping people out of poverty, but in demonstrating the compassion and generosity of the west in helping people who are less fortunate than we are. Where I think the hon. Gentleman is wrong is that we have to understand that a fundamental cause of the extremism and terrorism that we saw with al-Qaeda in Afghanistan, and that we see with ISIL in Syria and Iraq, is the poisonous ideology of Islamist extremism. We see people joining it who have not suffered poverty or deprivation, but they have bought into that perverted world view. Irrespective of what we might think of them, they are very clear that they want to kill us.
