Given Tony's resources, why hasn't he found the Defenders? Especially considering the fact that all four reside in New York City (the same city where Spidey lives) and three of the four have done precisely nothing to protect their secret identities.
Jessica Jones, Luke Cage, and Danny Rand should have been on Iron Man's radar for quite a while now. And considering how easily Tony tracked down Peter, figuring out Daredevil's secret identity should've been a walk in the park.
The fact that Tony went to New York to draft Spidey to his Civil War team, but ignored the four superheroes just one borough over is utterly perplexing.
The Defenders could have assisted with Captain America's capture and any other events that required superheroes.
So, Why Tony hasn't recruited them yet?
