President Obama said the US was still in the planning process for a response to the chemical weapons attack in Syria.
He added that no one is more "war weary" than him but the US must be willing to safeguard international norms.
The US is considering a "limited act" in response to the alleged use of chemical weapons by the Syrian army, but how will Assad respond?
Will America go it alone in Syria after the Government's defeat in the Commons last night? The answer is yes. Emphatically yes.
As the West wakes up to another day, it is not just Prime Minister David Cameron who has a Syria problem - so does President Barack Obama.
