Syria's deputy foreign minister Faisal Mekdad has said "we are still ready and waiting for any American aggression"
"If we suffer, other Arab countries will suffer in the future", he added.
"The main winner" from President Obama's decision to refer to Congress, says Mr Mekdad, "is Israel, as Congress is pro Israel".
He also warned that any American aggression will have "dangerous consequences" and all international organisations will pay the price.
Mr Mekdad also again denied that the Syrian army launched a chemical attack in Damascus, saying:
"Any crazy people can make a chemical weapons attack. We're against chemical weapons."
Syrian government officials were watching President Obama's White House speech. I didn't see them smile but there's no doubt they did.
Footage has emerged which appears to show an horrific incident incendiary weapons in northern Syria near a school.
After last week's clouds of poison gases in the suburbs, people in Damascus are bracing themselves for the expected missile retaliation.
