Obama Flash 90

US President Barack Obama said Wednesday the United States’ credibility, as well as that of the international community, are on the line over its response to the use of chemical weapons in Syria.

Obama spoke at a press conference in Sweden during a stopover that was intended to build support for intervention in the Middle East.

He said: “My credibility is not on the line. The international community’s credibility is on the line.

He added: "The question is, how credible is the international community when it says this is an international norm that has to be observed? The question is how credible is Congress when it passes a treaty saying we have to forbid the use of chemical weapons?"

Obama, en route to the G20 summit in St Petersburg, added he was “always hopeful” Russia’s Vladimir Putin would change his position on backing Syria’s Bashar al-Assad.

Putin said earlier he would not rule out supporting strikes against Syria – if it is proved President Bashar al-Assad used poison gas against his own people.
