US Defence Secretary Chuck Hagel has said that for a diplomatic solution in Syria to have any chance of succeeding, there is still a need for a "real threat" of US military action.
All of us are hopeful that this option might be a real solution to this crisis. Yet, we must be very clear-eyed and ensure that it's not a stalling tactic.
For this diplomatic option to have a chance of succeeding, the threat of a US
military action - the credible, real threat of US military action - must continue.
