Like, duh. If you have a lot of Iron Man suits, you use those Iron Man suits to blow things up. Especially bad guys. If you don't enjoy doing that, then don't be Iron Man! Go be Peace Corp Man instead.
Of course, if Tony Stark did pull this stunt off, we'd have no Iron Man 3 to watch. Which, incredibly entertaining as it was, wouldn't exactly be a terrible thing, now would it. Spoilers if you watch the hilarious animation video of Iron Man 3 made by HISHE, obviously. [HISHE]
