'It is a debacle': Mary Trump warns uncle about to set off 'catastrophic' crisis

President Donald Trump's niece on Tuesday flagged a potentially catastrophic consequence of his war with Iran.

Mary Trump, a psychologist and author, argued in a new Substack essay that the disruptions to the global fertilizer market caused by the closure of the Strait of Hormuz will have a much more devastating impact on the world than the spike in energy prices. The Strait has been closed since late February after the U.S. and Israel conducted a coordinated bombing campaign across Iran.

"The closure of the Strait of Hormuz is not just disrupting energy markets. It is disrupting fertilizer flows that determine future harvests. That disruption is setting the stage for a delayed but potentially catastrophic global food shortage," Mary Trump wrote.

"The Strait’s closure is now threatening the planting season for farmers across South Asia, Sub-Saharan Africa, the Middle East and North America," she added. "Those farmers are going to produce less food as a result, and that food scarcity is going to drive prices up globally. The people who will feel it first and be hit the hardest are the people who are already struggling to survive."

"It is a debacle. It is a catastrophe. There is no immediate solution. There is no agreed framework. There is no clear timeline for resolution. And Donald does not appear to be in any rush," she continued.
