From what was explored in both episodes that are character insights in my Marvel Cinematic Universe series, both Steve Rogers and Tony Stark's beginnings are within the realms of war, whether that be participating in one or being someone in the background moving the pawns around, so to speak. Both, to begin with anyway, revolve around war, weapons and armies that have the attitude of protecting America from outside threats. However, if you think about it in the most extreme and blunt version, Steve is an experiment to give the army an edge, a secret so to speak, whilst Tony creates his edge and presents it and himself to the world without thinking about the consequences. One quiet and one loud, but both getting to the same conclusion about protection. This connection of war is still relevant when they disagree in Civil War, when, through their own personal story arcs and experiences, choose a different route for the same cause. The cause, of course, being the protection of Earth from potential threats. Tony chooses security, and Steve chooses the freedom to fight back. One defence, one offence. And if you think about it, at the beginning, in their own separate films, they were the other way around. Copyright to Two Takes Podcast
