President Donald Trump is weighing whether to strike Iran as the conflict between Israel and Iran entered its sixth day. On social media, Trump demanded unconditional surrender from Tehran, without detailing what that would mean. Trump also said Washington knew the exact location of Iran’s supreme leader, Ayatollah Ali Khamenei, though he said the United States had no plans to target him, “at least not for now.” Trump’s remarks come at a time of weakness for Tehran, whose power is at a low ebb after a year of Israeli attacks against its regional proxies.
