That assessment is no longer merely a partisan stance. On Sunday, Sen. Dianne Feinstein, the top Democrat on the Senate Intelligence Committee, added her voice to that argument for further military action against ISIS.
"I happen to agree with what they said," Feinstein said on NBC's "Meet The Press."
On the one hand, Feinstein said, "The president is wise in this sense: What I understand he is trying to do is give an opportunity for this new Iraqi government to begin to make the moves which offer an alternative to the Sunni people."
But Feinstein warned that ISIS, the jihadist group that originated in Syria and has since spread into Iraq, could pose a direct threat to the U.S. Embassy in Iraq and is moving quickly toward that target.
"I believe their goal is Baghdad," Feinstein said. "It's very, very serious, and we have to have a strategy to deal with this in Syria and Iraq."
