Trump is busy on Truth Social today:
Mexico continues to violate our comprehensive Water Treaty, and this violation is seriously hurting our BEAUTIFUL TEXAS CROPS AND LIVESTOCK. Mexico still owes the U.S over 800,000 acre-feet of water for failing to comply with our Treaty over the past five years. The U.S needs Mexico to release 200,000 acre-feet of water before December 31st, and the rest must come soon after. As of now, Mexico is not responding, and it is very unfair to our U.S. Farmers who deserve this much needed water. That is why I have authorized documentation to impose a 5% Tariff on Mexico if this water isn’t released, IMMEDIATELY. The longer Mexico takes to release the water, the more our Farmers are hurt. Mexico has an obligation to FIX THIS NOW. Thank you for your attention to this matter!
I'm sure there is more than one side to this story but it's one that nags at one of the classic geopolitical angsts -- water.
