The Israeli war with Hezbollah over the summer, continuing loss of life in Iraq, the Iranian decision to defy the UN over its uranium enrichment programme and the violence faced by our forces in Afghanistan all give cause for concern.
These events in the Middle East pose major challenges to the world order of the 21st century. Institutions which secured peace since the second World War all have to re-assess their role, in light of shifting influences posed by radical fundamentalism, the rise of China and rehabilitation of Russia.
The UN's credibility is at stake in responding to Iran's defiant insistence on expanding its potential to create nuclear weapons. The Security Council, which presently includes Egypt and India, seems split over sanctions.
NATO has taken over peace-keeping in Afghanistan, beyond its traditional boundaries, where its mission is fast expanding to pursuing a war against the Taliban and Al-Qaeda.
The EU is seeking to develop its foreign policy and defence capabilities by some member countries taking the lead in the Lebanon.
Where does all this leave Britain? Our forces are doing a magnificent job in Iraq and Afghanistan, but seem under-equipped and over-stretched. The Government must give them the resources they need.
Yet Britain's place in the world is different in this new century. We should recognise our limitations and focus on our strengths. Committing our troops not just in solidarity with our US allies, but when our vital interests are threatened too. But if terrorists who threaten London are trained abroad, then it is in our interests that they are stopped, by force if necessary.
