Kathmandu. US President Donald Trump has repeatedly set deadlines, presented demands and issued threats during the five-week US-Israeli war against Iran. But rarely were they so clear. A new round of attacks against Iran will be devastating. That Tuesday will start at 20:00 Washington DC time 9:00 GMT on Wednesday. Within four hours, every bridge and power plant in the country will be "destroyed".

"Very little is off limits," Trump said Monday. According to him, to avoid such a fate, Iran should make an agreement "acceptable to it" and that agreement should also include the provision of "unimpeded transportation of oil" through the Strait of Hormuz. As the final hours pass, there is little sign that Iran is ready to agree to Trump's deadline. They have rejected a temporary ceasefire and issued a list of their demands. A US official called the demands "extremist". This has troubled the US President. If no deal is reached, Trump could extend his deadline for the fourth time in three weeks.
