1. Tony Stark Gives The Mandarin His Home Address - Iron Man 3
The Decision: After his bodyguard Happy Hogan (Jon Favreau) is badly wounded in The Mandarin's attack on the Chinese Theatre, Tony Stark issues an angry challenge to the Mandarin; he gives him his address and even cockily says, "I'll leave the door unlocked."
Why It's Stupid: Typical Tony Stark arrogance, you might be tempted to think? Not quite. In a rare move, Tony completely underestimated the powers of his enemy, for The Mandarin responds by sending a fleet of helicopters to fire rockets into Tony's home, completely destroying it and damn-near killing Tony, Pepper and Maya Hansen in the process. This sends Tony on an epic(cally annoying) journey, in which he has to make do with an improvised Iron Man suit for a while, and really, this all could have been avoided had Tony not been so brazen about a fight at his home.
