Reuters report via Axios says President Trump could postpone planned military action against Iran if a diplomatic deal appears viable.
White House doubts extending deadline, signaling time for diplomacy before Trump's 8 PM ET Tuesday deadline for Iran to reopen Strait of Hormuz.
Some officials say Trump is less optimistic about a deal and may issue final strike orders as early as Tuesday evening.
Trump previously threatened to target Iran's power plant, bridges, and said the entire country could be "taken out" if deadline missed.
