Today the UN security council will debate a UK-drafted resolution containing a rather gentle entreaty to the warring parties in Yemen. It will ask them to take "constant care to spare civilian objects, including those necessary for food production, distribution, processing and storage". If that sounds like the safety instructions for a new vacuum cleaner, then welcome to the world of UN resolutions. But what it actually reveals is a far darker, more shameful truth.The truth of a Saudi-led coalition, armed by Britain and the United States, which from the very start of the conflict in 2015 has sought to use starvation as a weapon of war. Their on-off blockades of any ports and airports controlled by the Houthi rebels have drastically cut supplies of food to a Yemeni population that relies on imports to eat. But far more insidiously, and in the absence of imports, the Saudi air force has systematically and deliberately destroyed the domestic means of producing and distributing food inside Yemen. Their bombs have constantly targeted agricultural land, dairy farms, food processing factories, and the markets where food is sold. these are no mistakes. These are medieval tactics with modern weapons deliberately employed by the architect of the Yemen war - Crown Prince Mohammed bin Salman - in an attempt to bring the rebel-held areas of the country to their knees. He could not care less about the impact on Yemen's civilian population, any more than he cared about what happened to Jamal Khashoggi.
