Vault-Co heard the train whistle approaching ten years ago.
The West has now been run down under the wheels of that train. They now realize there may be a problem. Russia is preparing to fight the war of the future. America is still getting ready to fight World War Two. While the United States has been sleeping, Russia has been mass producing ships and subs invisible to radar, high yield nuclear cruise missiles and a dozen other weapons that sound like they came from a John Campbell science fiction story.
The United States just hasn't lifted it's game. It doesn't even seem to know the game has started. It is to be expected when they figure this out, it will be right after they have lost.
