TIMELINE
2012
After the Avengers vs. X-Men battle, Captain America assembles a team of both humans and X-Men in order to help improve the public perception of Mutants. Red Skull, going after Mutants, steals Professor Xs body and cuts out his brain and eats it to harass Xavier's telepathic abilities.
2014
During a battle with an enemy called the Iron Nail, the Super-Soldier Serum within Rogers's body was neutralized, causing him to age rapidly to match his chronological age of over 90 years. No longer able to take part in field missions but retaining his sharp mind, Rogers decided to take on a role as mission coordinator, organizing the Avengers' plans of attack from the mansion, while appointing Sam Wilson as his official "replacement" as Captain America.
2016
During the Avengers: Standoff!, Steve Rogers learns from Rick Jones that S.H.I.E.L.D. has established Pleasant Hill, a gated community where they use Kobik to transform villains into ordinary citizens. When Rogers is brought to Pleasant Hill, he confronts Maria Hill about the Kobik project. During an attempt to reason with Kobik, Rogers is attacked by Crossbones. Before Rogers can be killed, Kobik uses her abilities to restore him back to his prime.
In Captain America: Steve Rogers #1, the final panel apparently revealed that Rogers has been a Hydra double-agent since his early youth. This is subsequently revealed to be the result of Kobik's restoration of Rogers' youth, as she had been taught by the Red Skull that Hydra was good for the world and Kobik changed reality so that Rogers would be the greatest man he could be, believing Hydra to be good, Kobik permanently altered reality so that Rogers had always been a member of Hydra. It is revealed in later issues that Kobik affected the entire Marvel Universe with her changes: that Rogers' memories are real ones, not fake ones.
Post Standoff, Winter Soldier reestablishes the Thunderbolts with Kobik in tow.
During Civil War II, with the discovery of new Inhuman Ulysses who has the ability to "predict" the future, Rogers was set out to prevent Ulysses from learning of his true plans and allegiance. Rogers did this by forcing certain predictions on him, such as anonymously providing Bruce Banner with new gamma research to provoke a vision that would drive Hawkeye to kill Banner, although this plan has apparently backfired with a recent vision showing the new Spider-Man standing over the dead Steve Rogers. After that vision sets off the final fight between Iron Man and Captain Marvel which resulted in Iron Man knocked to a coma.
2017
Post War, Rogers has been given the command of SHIELD after Maria Hill was revoked command post Standoff. However, Rogers has also been housing Chitauri pods in order to lure swarms of Chitauri to Earth, as the creatures want to instinctively find a queen and would destroy anything in their path.
After pressure from the public and the beating of former New Warrior, Rage, Sam Wilson relinquishes the title of being Captain America.
The Thunderbolts are later found by Baron Zemo and forces some of them to rejoin the Masters of Evil with him, Madam Hydra and Steve. Bucky later is sent to the past, Quantum Leap style where Kobik reveals that she think HYDRA are the good guys and wants Bucky to join.
After the Uncanny Avengers defeat Red Skull and called Beast to cut out the Xavier portions of his brain, Red Skull is depowered and Rogers detains him only to reveal he no longer works to accomplish Red Skull's vision of HYDRA and kills him.
