Iran shoots back at Trump: "Color us unimpressed"

“COLOR US UNIMPRESSED,” Iran’s Foreign Minister Mohammad Javad Zarif tweeted Monday night, employing Trump’s penchant to use all capital letters in his tweets.

“The world heard even harsher bluster a few months ago. And Iranians have heard them — albeit more civilized ones — for 40 yrs. We’ve been around for millennia & seen fall of empires, incl our own, which lasted more than the life of some countries. BE CAUTIOUS.”
