05/01/13: The Hill reports President Obama further blurred the “red line” he has imposed against Syria over chemical weapons on Tuesday, declining to lay out specific consequences if the line is crossed but reiterated that it would be a “game changer” for the entire international community. Asked about possible US military action if it’s confirmed Syrian President Bashar al-Assad’s forces have used chemical weapons, Obama said only that the administration would “rethink the range of options” available. As the President sounded a cautious tone, however, there were reports Tuesday afternoon that he might be planning to take new steps, including that Obama is now ready to provide arms to the opposition, although he had not made a final decision. National Security Council spokeswoman Caitlin Hayden declined to confirm or deny that report. Obama also spoke by phone Monday with Russian President Vladimir Putin, a strong supporter of Assad, about the chemical weapons allegations.
