Y’all acting like predicting an alien threat to MCU’s Earth is some wildly amazing thing that no one could do unless they were ‘paranoid’!
Aliens have already attacked! They actually attacked out of a big giant hole in the sky! And they whooped our asses but for the grace of six people, some really brave police/firemen, and a re-directed nuke. We also have big shiny fuck-off energy stones all around our earth that are clearly not from around here that people keep fighting over, and we know that Loki wasn’t acting alone.
Tony was the only one who saw the full might of what one attack brought, Tony is the only one beside Thor (and Fury) that is appreciating just what kind of force could be brought to bear against Earth, but Tony has apparently informed these suckers multiple times about what they’re up against and nobody chose to listen. Also Tony, “The Futurist is here!”, Tony Stark, Actual Genius, has been established as hyper-vigilant about future threats, both homegrown and far-flung.
Tony already had a plan in place for preparing for extraterrestrial threats before Wanda fucked with his head and before the Mind Stone fucked with Ultron that wasn’t ready for implementation but was a big idea in his head. “But his PTSD just made him paranoid” yes his PTSD is a big part of his character, so thrilled you finally noticed, he still did it and no one else did and this has been established for multiple movies so take your L and piss off.
