Barack Obama On The Strength Of Negotiating

One of the clearest policy -- and personality -- contrasts in the debate came when Barack Obama and John McCain discussed the issue of negotiating with other nations.

After McCain attacked him (angrily) for being open to negotiations, Barack Obama explained why negotiating is actually puts the United States in a stronger position, and why McCain's view is actually weak.

As he wrapped up his answer, Obama also hit McCain's refusal to commit to meeting with Spain -- a NATO ally.
