The UK's Counter Terrorism Strategy is divided into four elements: Preventing, Pursuing, Protecting and Preparing. The most effective way of fighting terrorism is by having a robust law enforcement system which can gather and analyse intelligence on terrorists, effective police forces able to investigate their crimes; and by having the legislation in place so that they can be prosecuted properly and quickly. Throughout the UK's presidencies of the EU and the G8 this year, the UK has been developing a co-operative international approach. This co-operation is essential to achieve long-term success in the fight against terrorism.
