Americans got bored with hearing about Vietnam before they got out of Vietnam; Americans got bored with hearing about Watergate, and what Nixon did or didn't do--even before the evidence was all in. Americans are already bored with Nicaragua; by the time these congressional hearings on the Iran-contra affair are over, Americans won't know (or care) what they think--except that they'll be sick and tired of it. After a while, they'll be tired of the Persian Gulf, too. They're already sick to death of Iran.
As I reported before, the wonderful K has leant me a copy of John Irving's novel A Prayer for Owen Meany (1989).
