There is much truth and sadness in Kissinger's essay. The conclusion that a President cannot conduct a winnable campaign without a proper declaration of war from Congress is persuasive. Everyone must fight a war, not just the soldiers. This basic reaffirmation of our Constitution on the author's part is commendable.
However, the other side of the coin, that public debate must be restrained demonstrates that the author, even after a decade of reflection, still does not appreciate American principles. Perhaps we're still too close to the Vietnam era. Perhaps another decade is needed.
