Via Obsidian Wings, I think this speech by Tory Leader David Cameron perfectly exemplifies the type of commitment embodied in the Euston Manifesto.
I fully appreciate the scale of the threat we face. I believe that the leadership of the United States, supported by Britain, is central to the struggle in which we are engaged.
I believe that the neo-conservatives are right to argue that extending freedom is an essential objective of western foreign policy.
And I agree that western powers should be prepared, in the last resort, to use military force.
We know from history that a country must be ready to defend itself and its allies.
More than that, we and others are justified in using pre-emptive force when an attack on us is being prepared, and when all means of peaceful dissuasion and deterrence have failed.
Furthermore, I believe that we should be prepared to intervene for humanitarian purposes to rescue people from genocide.
But I believe that in the last five years we have suffered from the absence of two crucial qualities which should always condition foreign policy-making.
Humility, and patience.
These are not warlike words.
They are not so glamorous and exciting as the easy sound-bites we have grown used to in recent years.
But these sound-bites had the failing of all foreign policy designed to fit into a headline.
They were unrealistic and simplistic.
They represented a view which sees only light and darkness in the world - and which believes that one can be turned to the other as quickly as flicking a switch.
I do not see things that way. I am a liberal conservative, rather than a neo-conservative.
Liberal - because I support the aim of spreading freedom and democracy, and support humanitarian intervention.
Conservative - because I recognise the complexities of human nature, and am sceptical of grand schemes to remake the world.
A liberal conservative approach to foreign policy today is based on five propositions.
First, that we should understand fully the threat we face.
Second, that democracy cannot quickly be imposed from outside.
Third, that our strategy needs to go far beyond military action.
Fourth, that we need a new multilateralism to tackle the new global challenges we face.
And fifth, that we must strive to act with moral authority.
Would that American politicians (of any party) could speak of those ideals (much less implement them).
