The Chinese, for their part, are thought by many to be equally in the dark about Washington’s program and about the United States more generally.
It is, again, impossible to say what exactly President Clinton was thinking in 1998, unable to anticipate the massacre of 2001. But it would not be unreasonable to assume that he was thinking a lot more about Monica Lewinsky and Newt Gingrich than he was about Osama bin Laden and Mullah Omar.
