"Lessons for an exit strategy."
You don't have to agree with Kissinger. But if you're serious, you do have to read and carefully consider his points. Kissinger's handling of Vietnam may have earned him lifelong enemies among the '68ers, but by doing so he showed the Russians that we were serious enough that sending tanks to the Saudi oilfields was going to be a non-starter. In short, the guy has played the game at a level most of us will never have to even consider.
