So you're saying the coal in Yemen = aid from within Yemen itself, in training its own doctors by its own internal medical university.
No. Yemen is incredibly wealthy in oil and natural gas reserves. The socialist government was deposed and a puppet set up by the Saudi who cannot allow a functioning socialist society beside their dictatorship. Yemen's potential wealth (coal) is why they are suffering so severly, in my.opinion.
It's interesting that in its largest territorial expanse, the Ottoman Empire once ruled from Hungary to Yemen. I'm just watching the dominoes fall and reading the tea leaves here, but maybe some Order will come to light to make a human-realized solution to end the proxy wars and religious wars that plague the Middle East. Something Christian, Semetic, and Islamic where everyone realizes that the efforts of the past 2000 years or so have been to create a system that works for everyone and makes sense in both a religious or humanist and lawful way.
People are ignorant in the Western Hemisphere to think that States only exist in the United States and the idea of state in international law is something even more ambiguous yet ideal as far as regulating chaos goes. I think finding common ground in history and tying knots between branches viewed as mortal enemies would be a good breather for the people on this planet. I hope we get to see it.
