Trump threatens to 'militarily complete the job' in Iran if attacks don’t stop

President Donald Trump responded to the most recent Iranian attack, which led the U.S. to retaliate for the second time since the memorandum of understanding was signed, by threatening to “militarily complete the job” if Iran doesn’t stop striking.

He said that Iran violated the ceasefire “again.” He had previously said that Iran’s first strike was a “foolish violation of the ceasefire agreement.”

"United States aircraft just struck Iranian missile and drone storage locations, and coastal radar sites, for violating the Cease Fire Agreement, AGAIN! It is very possible that they will never learn!” Trump wrote in a post on social media Saturday evening.”

“There may come a point when we are no longer able to be reasonable, and will be forced to militarily complete the job that we very successfully started,” he wrote, adding, "If that happens, the Islamic Republic of Iran will no longer exist!"
