But given the premise of Nixon and the Washington D.C backdrop movie has going for it, it will probably be politically motivated.
That is actually pretty interesting. What if it isn't the X-Men who are trying to alter time/space? In the comics, Bishop wanted to kill Hope (when she was a baby) because he thought she was what created his awful timeline. What if Bishop is the one that goes back with a nefarious plan and it's up to the future X-Men to follow him somehow and stop him?
However, I still want a political conspiracy story to be the impetus.
