If the world makes the right choices now - at this time of destiny - we will get there. And Britain will be at Americas side in doing it.
The other area is energy policy. Fuel is our economic lifeblood. The price of oil can be the difference between recession and recovery. The western world is import dependent. We base our policy on diversity of supply. You in the US import from 50 different countries, no one of which supplies more than 15 per cent of total imports. The EU pursues roughly the same policy.
So: who develops oil and gas, what the new potential sources of supply are, is a vital strategic question. We have the best energy companies in the world. Yet I don't believe that collectively, we have a sufficient strategy for ensuring that the political and corporate world co-operate together in ensuring the diversity of supply continues or in our policy towards energy.
The Middle East, we focus on naturally. But the Caspian, Russia and Angola will be vital sources of supply in the future. Sorting out the problems - for example conflict resolution in Angola which accounts for some 7 per cent of non-OPEC US imports - is not time wasted. Neither is collaboration on research for the fuels of the future or for greater fuel efficiency. This generation may not thank us for it, but our children's generation will.
My basic argument is that in today's interdependent world, we need an integrated approach, a doctrine of international community as I put it before, based on the values we believe in. I am not suggesting, incidentally, that nothing is done without unanimity in the world. That would be a recipe for the lowest common denominator - a poor policy. I am arguing that the values we believe in are worth fighting for; they are in the ascendant and we have a common interest in standing up for them. We shouldn't be shy of giving our actions not just the force of self-interest but moral force.
And in reality, at a certain point these forces merge. When we defend our countries as you did after September 11, we aren't just defending territory. We are defending what our nations believe in: freedom, democracy, justice, tolerance and respect towards others.
What makes America great is not its GDP alone or its military might. It is its freedom, its enterprise, its rejoicing in its different colours and cultures, the fact that someone of humble beginnings can aspire, work hard, succeed and be applauded for their success. And can disagree. When I pass protestors every day at Downing Street, and believe me, you name it, they protest against it, I may not like what they call me, but I thank God they can. That's called freedom.
Usama bin Laden's philosophy is not just a security threat to us. It's an assault on our hearts and minds. It represents extremism, cruelty, intolerance of different cultures and lifestyles. It can't be fought just with guns. It must be fought by moderate Islam against extreme Islam, by the virtues of religious and political tolerance triumphing over bigotry. Likewise, what happens in Africa offends every criterion of justice and decency we believe in.
Fighting for these values is a cause the world needs. The great paradox of our modern world is that we have the unlimited possibility of scientific and technological advance, the prospect of prosperity my father could never have dreamed of as a child. Yet we also have the capacity to destroy ourselves. The very interdependence we have, can be for good or ill. What makes the difference is the values that govern it.
All this has been latent in world politics for some time. September 11 brought it into sharp relief. When an event of such magnitude occurs only a fool fails to reflect and consider. It does change everything.
For America, it has laid bare the reality. American power affects the world fundamentally. It is there. It is real. It is never irrelevant. It can affect the world for good or affect it for bad. Stand aside or engage, it never fails to affect.
You know I want it engaged. Under President Bush, I am confident it will be and for good.
But if that's what I and many others want, it comes at a price for us too. It means we don't shirk our responsibility. It means that when America is fighting for those values, then, however tough, we fight with her. No grandstanding, no offering implausible but impractical advice from the comfort of the touchline, no wishing away the hard not the easy choices on terrorism and WMD, or making peace in the Middle East, but working together, side by side.
That is the only route I know to a stable world based on prosperity and justice for all, where freedom liberates the lives of every citizen in every corner of the globe.
