This is the current President of Syria, Bashar al-Assad. In this image he displays a very subtle example of Lip Pursing. Most episodes of pursed lips are easier to spot, and they are all usually very evanescent. Lip pursing is a sign of disagreement with what is being seen and/or heard - and it is a very reliable sign that an alternative plan is held or being considered. Interestingly, it usually is made in the context of authority and confidence. It also is a signal that the person who bears this expression is intent on taking action and has the means to do so. Their plan, at least in some significant part, will be implemented - and often often clandestinely. If you see this, do not dismiss it - for it may be your only warning.
