Trump was warned of likely Iranian retaliation on Gulf allies: report

President Donald Trump was ​warned that attacking Iran could trigger retaliation against U.S. Gulf allies despite his claims on Monday (March 16, 2026) that Tehran’s reaction came as a surprise, said a U.S. official and two sources familiar with ​U.S. intelligence reports, Reuters reported. 

Pre-war intelligence assessments did not say that Iran’s response was “a guarantee, ⁠but it certainly was on the list of potential outcomes,” said one source, who like the other two requested anonymity to discuss the issue.

The president twice on Monday (March 16, 2026) said that Iran’s retaliatory strikes against Qatar, Saudi Arabia, ‌the United Arab Emirates, Bahrain and Kuwait were a surprise, the first time at a Kennedy Center board meeting in the White House, according to Reuters.
