It is only after the two return to the present that Stewie learns that Brian deliberately ran into his past self while using the bathroom and told him about the September 11 attacks ahead of time , allowing the Past Brian to beat American Airlines Flight 11 hijackers Mohamed Atta and Abdulaziz al-Omari with a baseball bat , and then preventing the other three planes from leaving the airports . While watching the local news , it 's also discovered that former President George W. Bush , who has lost the 2004 election due to being unable to exploit peoples fears without 9/11 , has returned to Texas which has seceded from the United States , along with the rest of the southern United States , reforming the Confederate States of America , resulting in a Second American Civil War . Brian insists that things will still be better in the end , but when they travel five years into the future they find a computer generated post-apocalyptic future caused by nuclear attacks all across the United States which results in the deaths of over 17 million people ( including Cesar Millan much to Brian 's horror )
