From a geo-strategic point of view, I consider Iran a bigger problem than the Islamic State. ISIS is a group of adventurers with a very aggressive ideology. But they have to conquer more and more territory before they can became a geo-strategic, permanent reality. I think a conflict with ISIS - important as it is - is more manageable than a confrontation with Iran.

The attitude of the West and of Russia towards a crisis like Ukraine is diametrically different. The West is trying to establish the legality of any established border. For Russia, Ukraine is part of the Russian patrimony. A Russian state was created around Kiev about 1,200 years ago. Ukraine itself has been part of Russia for 500 years, and I would say most Russians consider it part of Russian patrimony. The ideal solution would be to have a Ukraine like Finland or Austria that can be a bridge between these two rather than an outpost.

In the current [Carter] administration, who can use the White House swimming pool and tennis courts is decided at the very highest level. President Ford did not bother himself with such minor details. He let me swim in the pool. He only got upset when I tried to walk across the water.

In my particular case foreign policy happens to be my hobby, my consuming interest. I had spent decades studying it.

I have great respect for the Taiwanese. They have done an extraordinary job. But it was not a sustainable position to say that the legitimate government of China resides in Taiwan, which at that time didn't have much contact with the mainland.

Our nation is uniquely endowed to play a creative and decisive role in the new order which is taking form around us.
