WASHINGTON (CNN) - At the start of the Republican presidential debate, former New York City Mayor Rudy Giuliani was unwavering in his support for the United States' original decision to go to war with Iraq.
"Absolutely the right thing to do," Giuliani said. "It's unthinkable to leave Saddam Hussein in charge of Iraq and be able to fight the war on terror. And the problem is that we see Iraq in a vacuum. Iraq should not be seen in a vacuum. It is part of terrorist war against the United States."
Giuliani also took a jab at Democrats, saying they need to take the threat of Iran more seriously.
"The danger to us is a state like Iran handing nuclear weapons over to terrorists," he said. "So it has to be seen in that light and we have to be successful in Iraq."
