"Let me have one area of disagreement with the secretary," asked Sanders. "I think she said something like the bulk of the responsibility [for ISIS] is not ours. Well, in fact, I would argue that the disastrous invasion of Iraq, something that I strongly opposed, has unraveled the region completely and led to the rise of al Qaeda and to ISIS."
"Now, in fact, what we have got to do, and I think there is widespread agreement here, is the United States cannot do it alone," he continued. "What we need to do is lead an international coalition which includes very significantly the Muslim nations in that region who are going to have to fight and defend their way of life."
It was an interesting proposition: to solve the original sin of the Iraq War, the United States was going to have to undertake a coalition-led intervention in the same region.
Dickerson was quick to reopen the old wound: "When you say the disastrous vote on Iraq, let's just be clear about what you're saying. You're saying Secretary Clinton, who was then Sen. Clinton, voted for the Iraq War. Are you making a direct link between her vote for that war and what's happening now for ISIS?"
Sanders replied: "I don't think any sensible person would disagree that the invasion of Iraq led to the massive level of instability we are seeing right now. I think that was one of the worst foreign policy blunders in the modern history of the United States."
"If you look at history, John," Sanders said, "you will find that regime change, whether it was in the early '50s in Iran, whether it was toppling Salvador Allende in Chile, whether it was overthrowing the government of Guatemala way back when, these invasions, these toppling of governments, regime changes have unintended consequences. I would say that on this issue, I'm a little bit more conservative than the secretary," Sanders said, "and I am not a great fan of regime change."
