Iran responded to U.S. President Donald Trump’s address to Americans on the war with new missile attacks targeting Israel and the Gulf Arab states Thursday, underlining Tehran’s insistence that it rejected Washington’s outreach for a ceasefire while maintaining its grip on the Strait of Hormuz.

Israel and several Persian Gulf nations reported a new influx of drone and missile launches toward them early Thursday morning, hours after President Trump asserted in a national television address that the U.S. military campaign against Iran was an overwhelming success and “near completion.”

The speech comes amid Trump’s recent criticism of Nato allies, and his threats to leave the military alliance.

U.S. stock futures fell on Thursday morning after President Donald Trump indicated that the Iran war would continue. S&P 500 futures declined 1.15%, and Nasdaq 100 futures lost 1.5%. Futures tied to the Dow Jones Industrial Average slid 447 points, or about 0.96%.

Iran’s president has written an open letter to America asking whether the Trump administration’s war with his country is putting “America First.”

President Trump will address the nation "to provide an important update on Iran" as he anticipates the U.S. will end its military campaign soon.

The White House promised an “important update” on Iran, in what is set to be the president’s first prime-time address since the U.S. and Israeli assault began.

US President Donald Trump is signaling that he may walk away from the Iran war, unilaterally stepping out without toppling the Islamic Republic, opening the Strait of Hormuz or securing a deal with Tehran to halt attacks on the United States and its allies.

WASHINGTON/CAIRO, April 2 (Reuters) - Hopes for a swift end to the Middle East war faded on Thursday after U.S. President Donald Trump vowed more aggressive strikes on Iran, in an eagerly anticipated address that disappointed investors hoping for clearer signals of a way out.

Most want the war to end quickly, and opposition has hardened since it began, posing political dangers for the president and his party as the midterms approach.
