The government of Yemen has put itself in an impossible situation, where the only “friends” it has are, ironically, its ... enemies.from Don’t Let the British Turn Yemen into an Afghanistan!
For a crash course in the situation in Yemen, I suggest the above-referenced article. The gist of it seems to be that the British empire has been finely manipulating the situation there since it was a British colony, with what I assume has been an intent to cause it to spiral into chaos in this general time frame, as part of its plan to destroy civilization. It's not just trying to kill us because we're cluttering up its planet, but it, as a literal tool of the Devil, is trying to eradicate free will from the human race, as indicated here. Orwell's 1984 is based on knowledge of this plan, and Guantanamo is a sort of real-world Ministry of Love.
