US President Donald Trump has warned Syria’s President via twitter that he is messing with some extremely smart missiles.

“Believe me, al-Assad, he’s a bad dude,” Trump tweeted.

“Al-Assad is a lightweight – my missiles aimed at Syria are very stable geniuses,” said Trump.

“They are worth a lot of money.”

Trump says “crooked Hillary would have started WWIII if she attacked Syria but we’ll be winning big league”.
