Soooooo. you still haven't seen the video link?
From TDS? I watched the debate itself. WTF?
He didn't defend any point.
He defended several key points. He defended his statements about Obama going on the apology tour with quotes from said tour (which were accurate btw). He effectively countered Obama's claim that he hasn't been ignoring Israel. He also correctly defended his statements about allowing the car companies go into bankruptcy (which Obama got completely wrong btw).
What he didn't do was allow the President to drag him into an argument about other topics. He controlled what was debated. If you failed to see that then you weren't paying attention. He choose to steer the topics away from areas he knew the president would be prepared for and into areas he wasn't (or at least which Romney was much better prepared for).
He changed all of his points to agree with President Obama. If it weren't blatant contradiction, then you could have a point.
You're missing the point I made earlier. 99% of voters don't pay attention to foreign policy. He didn't change his positions. He just choose not to get into arguments about nuanced differences of positions which most voters aren't going to understand, but which would put the advantage into Obama's court. Romney outmaneuvered Obama on this debate.
