If you've worked together with somebody very well, leave-taking is very difficult. But we are all politicians. We all know that democracy lives off change. So, in the United States of America, the Constitution has very clear stipulations on this. It's a tough rule. Eight years and that's it, out goes the president and a new one comes in.

I want us to be able to preserve our level of prosperity. We must constantly remind ourselves that Germany has been eating into its capital. It is only through successful management that we can once again secure our foundation of prosperity and social security.

This conclusion of trade agreements that go beyond the scope of mere tariff agreements, customs agreements, are most important and I'm very pleased we were able to bring this to fruition between Canada and the E.U.

Neither the chains of dictatorship nor the fetters of oppression can keep down the forces of freedom for long.
