WASHINGTON (Reuters) - U.S. President Donald Trump said on Friday he wants to see action to fix the flaws he sees in the Iran nuclear deal in a short period of time, adding that he could end the deal instantaneously.  We ll see what happens over the next short period of time and I can do that instantaneously,  Trump told reporters when asked why he did not choose to scrap the deal now.  I like a two-step process much better,  said Trump, who was speaking shortly after he announced he would not certify the 2015 deal, aimed at preventing Iran from developing a nuclear bomb, in a major shift in U.S. policy. 
Trump says he can end Iran deal if no action to fix it soon
