I suppose that Obama is mad that Russia helped Syria to overrun the terrorists and also to trap dozens of american military advisors in Allepo, the ones secretly helping the terrorists.  Christmas was celebrated for the first time in Aleppo since 2012 and he's probably mad about it.  He's probably also wondering how its possible he/she lost the election after all the 'fake news mainstream media' like CNN, WP, among the many that claimed that Clinton was far in the lead.  As well, the multi billionaires George Soros and Bill Gates are building software to make sure that Facebook news is legit with their new news engine so that the candidates they support like Hillary will not lose again.
