America is the only superpower. But our leadership is being tested in the Middle East, and some of the things that we have done in the Middle East are contributing to a potential explosion region-wide. And if that explosion gets out of hand, we may end up being bogged down for many years to come in a conflict that will be profoundly damaging to our capacity to exercise our power, to address the problems implicit in this global awakening, and we may face a world in which much of the world turns away from us, seeks its own equilibrium, but probably slides into a growing chaos.

The American people have to think hard about their definition of the meaning of the good life, that hedonistic, materialistic society of high levels of consumption, increasing social inequality is not a society that can be part of the solution of the world's problems.

The United States can certainly defeat North Vietnam, but the United States cannot defeat a guerrilla war which is being raged from a sanctuary through a pattern of penetration, intervention, evasion, which is very difficult for a technologically advanced country like the United States to combat.

One has to define very clearly what one's objectives are, determine in advance how much one is prepared to pay to achieve that objective and then act accordingly.

To put it in a terminology that hearkens back to the more brutal age of ancient empires, the three grand imperatives of imperial geo-strategy are to prevent collusion and maintain security dependence among the vassals, to keep tributaries pliant and protected, and to keep the barbarians from coming together.

Moreover, they [the Central Asian Republics] are of importance from the standpoint of security and historical ambitions to at least three of their most immediate and more powerful neighbors, namely Russia, Turkey and Iran, with China also signaling an increasing political interest in the region. But the Eurasian Balkans are infinitely more important as a potential economic prize: an enormous concentration of natural gas and oil reserves is located in the region, in addition to important minerals, including gold.

Without Ukraine, Russia's imperial aspirations are essentially nostalgia, but it's not a real policy.
