The Vietnam analogy leaves out the broad cold war context for that human and military failure.

Here is where the Vietnam analogy does offer a valid lesson.

American diplomats insist, perhaps disingenuously, that they hate to apply the Vietnam analogy.

That's the Vietnam analogy people in the Administration keep coming back to.

I will say this: Vietnam analogies are really tempting, and I usually try to avoid them.

To that extent, the Vietnam analogy is perfectly apt.

Thinking back to the President's announcement speech a week ago, it was striking that he took time to specifically reply to (refute) the Vietnam analogy.

Forget the Vietnam analogy that critics of the Iraq war usually toss out.

Even in trying to contrast the two wars, invoking the Vietnam analogy was unusual for Mr. Bush.

Vietnam analogies are deeply imperfect when discussing the war in Iraq.
