The Attack on the White House was a pivotal moment in history essentially governing the fate of the future. A whole new timeline of events were spawned out of this moment changing all events after 1973.
After Logan, Charles, Beast, and Erik prevent Mystique from killing Bolivar Trask, Erik tries to kill her to protect the future. When Beast tries to stop him, this reveals the existence of mutants to the world and Erik manages to wound Mystique in the leg. After the incident, although they all manage to escape, Richard Nixon greenlights Trask's Sentinel program to protect the world against mutants and they manage to get a blood sample from Mystique on the sidewalk allowing Trask Industries to get what they need to create the future Sentinels.
- "You built these weapons to destroy us. Why? Because you are afraid of our gifts. Because we are different. Humanity has always feared that which is different, but I am here to tell you, to tell the world, you're right to fear us. We are the future. We are the ones who inherit this earth and anyone who stands in our way, will suffer the same fate as these men you see before you. Today was meant to be a display of your power. Instead I give you a glimpse of the devastation my race can unleash upon yours. Let this be a warning to the world and to my mutant brothers and sisters out there, I say this. No more hiding. No more suffering. You have lived in the shadows of shame and fear for too long. Come out. Join me. Fight together in a brotherhood of our kind, a new tomorrow that starts today."

With Trask not killed the dark Sentinel future was prevented from existing, changing history mostly for the better. Trask however was put in jail by President Nixon, in Magneto's old cell at the pentagon. Magneto would go on the run and eventually meet Magda Gurzsky. Mystique would go on to become a hero for young mutants but she would also go into hiding. Wolverine would be fished out of the river and would eventually be found by William Stryker and taken to Alkali Lake. Charles and Beast would reopen Xavier's school for new mutants. Also, the White House and the RFK Stadium began repairs having been damaged by Magneto.
As a result of this event in 2023 Wolverine would wake up in the X-Mansion, regaining his consciousness and memories from his travels to the 70's. He would find the school running normally and that Professor X, Cyclops, Jean Grey, Storm, Rogue, Iceman, Beast, Shadowcat and Colossus all alive and well.
