As expected, Trump has started the process for redesignating the Houthis as a foreign terrorist organization (FTO), and he is also going after USAID support for U.N. and humanitarian aid groups working in Yemen:
It also directs the US Agency for International Development to end its relationship with United Nations agencies, nongovernmental organizations and contractors “that have made payments to the Houthis, or which have opposed international efforts to counter the Houthis while turning a blind eye towards the Houthis’ terrorism and abuses.”
The Biden administration removed the Houthis from the FTO list for a very good reason, and it is a terrible mistake to put them back on. The Houthis are the de facto government of the part of Yemen where most of its people live. Labeling them as terrorists will do tremendous harm to the population. The sanctions that come with this designation threaten to cripple the economy, block remittances, and prevent the delivery of humanitarian aid. That is why humanitarian aid groups condemned the designation the first time, and it is why they are condemning it again now.
