"Both al Qaeda and now ISIL pose a direct threat to our people, because in today's world, even a handful of terrorists who place no value on human life, including their own, can do a lot of damage," Obama said.
In his eighth State of the Union Address, Obama said terrorist groups like al Qaeda and ISIL (also known as ISIS Islamic State militant group) use the Internet to poison the minds of individuals inside the country; they undermine American allies.
"That's the story ISIL wants to tell; that's the kind of propaganda they use to recruit," he asserted.
"We don't need to build them up to show that we're serious, nor do we need to push away vital allies in this fight by echoing the lie that ISIL is representative of one of the world's largest religions. We just need to call them what they are - killers and fanatics who have to be rooted out, hunted down, and destroyed," Obama said.
"With nearly 10,000 air strikes, we are taking out their leadership, their oil, their training camps, and their weapons. We are training, arming, and supporting forces who are steadily reclaiming territory in Iraq and Syria," he said.
"If this Congress is serious about winning this war, and wants to send a message to our troops and the world, you should finally authorise the use of military force against ISIL. Take a vote. But the American people should know that with or without Congressional action, ISIL will learn the same lessons as terrorists before them," the President said.
