完形填空

What seemed like an unplanned comment about Syria's chemical weapons (武器) had a major effect on world events this week. American Secretary of State John Kerry spoke last Monday at a press conference in London. He was reacting to questions about possible American action to answer a chemical weapons attack believed to be likely in Syria. One reporter asked the secretary whether there is anything Syria's president can do to avoid an American military (军事的) strike.

"Sure, he can turn over every single bit of his chemical weapons to the international society in the next week."

Mr. Kerry made it clear that he was speaking theoretically, and did not expect anything like that to happen.

But Russia seized on the idea and persuaded Syria to do the same. That brought plans for American congressional (议会) votes on military action to a halt. President Obama has said he would accept a diplomatic settlement if it can be carried out. But that would likely take weeks, at least.

Mr. Obama has said the government of Syrian President Bashar al-Assad must be punished for breaking the nearly century old ban on the use of chemical weapons. He called for American action to prevent future use of chemical weapons in Syria. He suggested limited airstrikes on government targets. The airstrikes could happen quickly if Congress approves.

Joanna Kidd is a security expert with London's King's College. She says any move to place Syria's chemical weapons under international control would take a long time, if it could be done at all.
