President Donald Trump will decide within the next two weeks whether to strike Iran, the White House said Thursday, saying Trump still sees a “substantial” chance that negotiations can achieve U.S. and Israeli demands on Iran’s nuclear program. Trump’s announcement, relayed by press secretary Karoline Leavitt, puts an extended timeline on the president’s warnings to Iran to immediately shut down its enrichment operations and any other potential for producing nuclear weapons. “Based on the fact that there’s a substantial chance of negotiations that may or may not take place with Iran in the near future. I will make my decision whether or not to go within the next two weeks,” Leavitt quoted Trump as saying.
