Advisers close to U.S. President Barack Obama have been drafted by David Cameron to help the Conservatives in their election campaign against Gordon Brown and Labour.
As I understand mr.Cameron is ready to follow blindly Washington in international affairs. Unlikely he would say something like:

The UK is an independent country and has own interests. We will not participate in unlawfull wars with unclear objectives.

Why it has been done? Washington is very influental and mr.Cameron seeks its support.
