Reuters reported that Elkin told Israel’s Army Radio on Friday that “there is a question here of when you set a red line, do you stand behind it?”

“Now that the Americans’ red line has apparently been crossed, there is a test,” he added. “It is clear that if the United States wants to and the international community wants to, it could act – inter alia, militarily – to take control of the chemical weapons, and then all the fears … will not be relevant.”

Elkin did not elaborate on what U.S. tactics he envisaged in the interview.

He said in the interview that he expected world powers to clarify their position on Syria “in the coming days.”
