I'm sure we've all seen the movie "Back to the Future." George McFly needs to take Lorraine to the Enchantment Under the Sea dance, so they can have their first kiss, set the timeline back to normal, and Marty will still exist. Because Marty interrupted the original timeline, George had to try to win Lorraine over, again.
The reason I'm bringing this up, is because George went through a transformation. The plan was to "rescue" Lorraine from Marty, and win her heart. While practicing what he was going to say, "Get your damn hands off of her," his heart wasn't in it, and he didn't even think he should swear! In the process of trying to save her from Marty, Biff took Marty's place. George's transformation didn't take place, until he realized that he finally had to stand up, be a man, and protect Lorraine. President Obama, tried to make the same transformation, recently. "...And I don't sit around just talking to experts because this is a college seminar, we talk to these folks because they potentially have the best answers, so I know whose ass to kick."
I'm sorry, Mr. President. But, you can't just act tough when you have never shown any proclivity to it in the past. George McFly didn't know how to act tough, because people had been walking all over him for all of his life. It wasn't until he actually felt angry, that he could actually summon up the genuine anger that was needed in that situation. Bottom line: You can't just act all tough when it isn't genuine, and expect the American people to buy it.
In addition, your "ass to kick" rhetoric was misplaced. While George had a genuine threat that he had assessed and dealt with appropriately, your tough guy act is completely inappropriate, especially given your agreement to deal with actual thugs like Mahmoud Ahmadinejad, Kim Jong Il, and Hugo Chavez without preconditions. Find a more appropriate time to try on your big boy pants, sir.
