In the past, the U.S. has shown its capacity to reinvent its gifts for leadership.

His (Lenin's)humanitarianism was a very abstract passion. It embraced humanity in general but he seems to have had little love for, or even interest in, humanity in particular. He saw the people with whom he dealt, his comrades, not as individuals but as receptacles for his ideas. On that basis, and no other, they were judged. He judged man not by their moral qualities but by their views, or rather the degree to which they accepted his.

They needed to believe; they wanted to be duped.
