US President Donald Trump has shared what is believed to be the day and the hour when American forces would strike Iran's critical civilian infrastructure if the Islamic nation does not open the Strait of Hormuz for global shipping. Some analysts said Trump's message could also be the new deadline for Iran to re-open the strait. Broadcasting the time of a military strike is an act likely never seen before in warfare. But Trump's methods during his presidency have been unconventional. His latest foul-mouthed threat to destroy Iran's infrastructure Sunday was the latest example. The threats followed the extraction of a US Air Force weapons systems officer whose F-15E Strike Eagle aircraft was downed inside Iran. In a post on Truth Social, the social media platform owned by Trump, the US president shared what is believed to be the time of the incoming attack on Iran.
