ISIS has taken more and more territory in Iraq and Syria, sometimes overrunning government forces while terrorizing civilians.
"They are beyond just a terrorist group," Defense Secretary Chuck Hagel said last week. "They marry ideology, a sophistication of strategic and tactical military prowess.
"This is beyond anything we have seen, and we must prepare for everything."
But on "New Day" Wednesday, Senator John McCain said President Obama hasn't presented a clear strategy on how to fight against the group.
When Alisyn Camerota argued Obama stated his goal was to contain ISIS, McCain replied: "You can’t contain ISIS, you have to defeat it.”
McCain attacked Obama for not presenting a strategy in the region, saying "this president doesn't want to lead."
But the lawmaker recommended that there should be airstrikes in Syria – both against ISIS and against Syrian President Bashar al-Assad.
"The ultimate goal should be the overthrow of Bashar al-Assad," McCain said.
