[MCU] In 2008, a military convoy was ambushed, killing several US service members...and the country’s foremost weapons developer. How do events play out in the MCU without Tony Stark?

The Avengers initiative continues, but the lack of Iron Man in the Battle of New York is a significant loss for the Avengers. Without Iron Man, a nuclear bomb is deployed in New York. Captain America, Black Widow, and Hawkeye are killed, but the Chitauri Invasion continues undeterred. The Chitauri defeat Thor and the Hulk and Loki becomes the ruler of Midgard. He has Thor watch his rise to power and kills Thor himself while Hulk is kept as a weapon for Loki's empire. HYDRA sees the writing on the wall and joins Loki's side. Because Loki wins and there is no Iron Man, War Machine, Ultron, Scarlet Witch, Quicksilver, or Vision, and with the death of Captain America, Bucky never turns to heroism. There is effectively no resistance that Loki cannot quell. Thanos' quest for the Infinity Stones is greatly accelerated by Loki's victory and the children of Thanos survive the ordeal.
