Up to a certain extent the UN soldiers are useful. But they are consuming a lot of resources in relation to the little work they are doing.

My own experience from a decade ago taught me I cannot trust the UN. But it is a world body and we have to live with it and tolerate it. But I can't hide my feelings about its inefficiency and its not being productive.

The efficiency of a President at the beginning of his term depends on their capacity to get everything under control. That was my case. But once the institutions have been put in place, and the responsibilities delegated, the leader becomes a reference, a referee, a symbol and unifying figure for the nation. The issue is how and when to recognize the moment when staying in power becomes counterproductive.

National security is vital for economic and social progress.

There are African leaders who have the dangerous habit of leading their people into an abyss. In Rwanda we've had presidents who killed. The one million people who died here were, to a certain extent, victims of their leader, President Juvénal Habyarimana, who died in a plane crash before the genocide began. He contributed to all that. The man who took over from him was running around ordering people to kill. If this president came back and landed in my hands, I would have him arrested and tried. Unfortunately, he died a natural death.

The West has institutions that can punish the misconduct of individuals. What drove Rwanda and Africa into decline was the fact that certain people weren't held accountable. When we move to make corrupt mayors or officers answer to the courts, people always immediately say that we are repressive. But should we allow these people to continue to get away with it?

It is better for a country to have a strong leader, this applies to the United States as well as to Rwanda.
