In a world where there appears to be a certain instability with one super state owning 40% of the world's weaponry, a state which cannot be challenged by anybody, it would be useful to have a Europe that had an equal influence around the world and would insist that the European voice is louder, stronger and more influential than at present. That is in the interests of all of us. It gives greater balance to foreign policy and ensures there are more people in a better place in a better Europe. Wherever we are, we have a duty to convince people on this issue.
