If this is "the world's biggest humanitarian disaster," then why haven't we heard of it. Like, at all?
I had to look it up and read a couple of articles to even find out where Yemen is, and I am a nerd who can spend hours flipping through the pages of an atlas. A quick summary for my fellow VCers: it's a dinky little side-piece on the south end of the Arabian peninsula. It has been unstable for most of its history, and was split into two different countries (by squabbling tribes) until 1990. Then the squabbling continued, erupting into a full-blown civil war, with the accompanying reductions in quality of life, such as lack of food and drinking water, and cholera outbreaks.
The Houthis are a band of Shiite rebels who were fairly successful after a decade's worth of attempts to overthrow their dinky little govt., except when they had the chance to join a coalition govt., they refused and went back to being a mere rebel faction. So the country continues to be politically unstable, exacerbating the economic and infrastructure problems, and continuing the violence, death and disease.
Though they deny it, intelligence reports say the Houthi are supplied with weapons and financing by Iran, which, by definition, makes them an enemy of the US and most other countries. One of their main tenets is "anti-imperialism," which in any Middle Eastern country is code for "Let's wipe out Israel and eventually the Europeans and the US."
So, if we do a little political-science math, and add up the obvious facts, we have this:
Anti-government rebel forces + Aggressively Anti-Western dogma + Backing from our Enemies (Iranian Govt.) = Terrorists
And you say Trump was wrong to classify them as such? Why? Is there something we're missing? There is some evidence of the Houthis combating Al Qaeda and/or Daesh (ISIS), but that is more likely them fending off the competition than any form of altruism. These people are not allies to the US, and are disavowed by a coalition of almost every other M.E. country, including Egypt, Jordan and Saudi Arabia. How is Biden not being a chump, by giving them anything but the finger?
