CHICAGO (CBS DC) – Former Secretary of State Hillary Clinton is warning that the Islamic State militants is a greater threat to the United States than any terrorist organization the country has faced before.

“It’s a serious threat because this is the best-funded, most professional, expansionist jihadist military force that we have ever seen,” she declared.

Speaking at the Economic Club of Chicago, Mrs. Clinton sounded the alarm about the Islamic State of Iraq and Syria’s wealth and leadership. “This is far more advanced and far richer than al-Qaeda ever was.”

Her comments were a slight change from August, when Clinton criticized President Obama for not arming moderate Syrian rebels earlier.

But she strongly supported the current campaign of airstrikes in support of moderate forces in the region and advised the mission be strengthened because ISIS”will attempt to launch attacks against Western targets if it has the ability to do so.”
