The document "Rebuilding America's Defenses" is readily available all over the internet. Here's one source.

The shock displayed by the Left at this document is rooted in the myth that America is the source of all the conflict in this world, and if we'd just pull back to our own borders, take the carriers out of the Gulf and elsewhere, remove our bases from nations we've kept free for fifty years, and leave the planet in a huge power vacuum, that somehow peace and permanent stability will spontaneously break out.

Tell me, who do you want keeping an eye on the Straits of Hormuz? The answer "nobody" is not a workable one and never has been.
