I found it particularly interesting when you talked about how the European model of integration is not really appropriate for our North American integration, but there are certain aspects we should be looking at that could be applicable to North American integration, like multi-layered, multi-speed, and the fact that even in Europe not all sectors have been integrated at the same time, not all countries within the European Union have integrated on common rules, or whatever, whether it's currency or other issues.
Tout cela me semble très intéressant; en matière d'intégration nord-américaine, vous avez signalé, monsieur Keyes, que la sidérurgie est sans doute l'une des industries les plus intégrées d'Amérique du Nord. En outre, la sidérurgie a constitué l'un des fondements même de l'Union européenne.
