Westerners who join ISIS and the threat the pose to the US

"You can't win", Blackburn said.

The focus of Washington - and much of the world - has shifted now to IS, which claimed responsibility for the coordinated attacks that killed at least 130 people in Paris on November 13.

The group responsible for the Paris terror attacks is "a bunch of killers with good social media", he said. Now, they're going additional.

National Security Advisor Susan Rice said after the press conference that the US agrees ISIS took down the plane. "The American people in the past have confronted a few very real, enormous threats".

With all due respect to FDR, one of the things we have to fear in 2015, is a tone-deaf president, who doesn't understand who the enemy is. And so, even as we destroy ISIL on the battlefield - and we will destroy them - we will take back land that they are now in. "This will be no different".

The president also pressed Russian president Vladimir Putin to align himself with the US-led coalition carrying out air strikes against Isis, noting that the militant group has been accused of bringing down a Russian passenger jet last month, killing 224 people.

"The most powerful tool we have for fighting ISIS is to say we're not afraid, to not elevate it, to (not) buy into their fantasy that they are doing something important", Obama said.

Obama said it "would be helpful" if Russian Federation directed its focus on tackling Islamic State and he hoped Moscow would agree to a leadership transition in Syria that meant its president stepping down. As the United States has turned its attention to defeating the Islamic State group, it has softened its stance about the urgent need to push out the Syrian leader.

Despite the mindset inside the White House that the public remains steadfastly opposed to another war in the Middle East, that same ABC News/Washington Post poll said 60% of those surveyed would support an increased use of ground forces against ISIS.

More than four years ago, Obama demanded that Assad leave power. "We can't stop the fighting".

In general, Obama's remarks in response to the Paris attacks, were shockingly tone-deaf to the outright fears of Parisians and anxiety being felt by Americans. Amid wall-to-wall and sometimes breathless television coverage of terror threats, Obama urged journalists to "maintain perspective".

The Islamic State has openly said they are infiltrating the refugee population to get into countries to cause problems, just as they did in France.

Obama, the son of a migrant mother and father, voiced his personal determination to face down anti-refugee measures that he has already threatened to veto.

It's been one week since the Paris attacks, and with each day's reports of more manhunts and raids, we've received new data points about the terrorist threat at hand - tidbits about how the Islamic State recruits Westerners, about how these radicalized individuals travel to Syria to fight and train, and about those who return home to help ISIS target Western cities.

The majority of the children at the centre were members of the Rohingya minority who've fled persecution, discrimination and ethnic violence in Myanmar, officials said.
