Steve Rogers, the MCU's original Captain America, cruised around the battlefields of World War II on a very fitting, very real historical motorcycle.

Another reason The First Avenger stands out from the rest of the Marvel Cinematic Universe is that, even though it ends by reminding us that Steve has awoken in the modern day, its final note is melancholic instead of triumphant. After Steve sacrifices himself and buries the Tesseract along with him, he wakes up 70 years later in an alien world.

This timeline tells us that Thunderbolts* will happen either soon after the events in Brave New World or a little later down the road. Whatever the case, Congressman James Buchanan Barnes will be elected to office before he and the Thunderbolts become the New Avengers.
