12 Dumbest Decisions In MCU History
11. Tony Gave The Mandarin His Home Address - Iron Man 3
After defeating Loki in the Battle of New York, the next villain that Tony Stark went toe to toe with was an old face from the past. Behind the guise of The Mandarin, Aldrich Killian was responsible for several bombings throughout the United States, and had threatened the life of President Ellis on more than one occasion.
Since Tony was still struggling with anxiety attacks and PTSD from seeing the other side of the dark wormhole a year earlier, this didn't truly register on his radar until one such blast almost killed one of his best friends, Happy Hogan.
Naturally, this got Tony's full attention, and made the entire thing personal. Iron Man consequently threw down a gauntlet to the terrorist known as The Mandarin which included giving him, and the entire world, his home address.
It should be common sense not to make such a threat to such a person and immediately tell them where you live, but particularly with how Tony was personally targeted and nearly killed by Ivan Vanko in Monaco, he should have known MUCH better than this. He didn't even get Pepper to safety!
