The Houthis are now shelling southern Saudi Arabia, and have even fired a missile into Riyadh. Yeah, I know, the poor Yemenis:
Yemen population 26.8 million (80% adult males armed)
Saudi Arabia pop. 31.5 million0 (25% adult males armed)
Fair enough. But considering it was Saudis who murdered 3000 people on 911, I wonder why I should care about their well being.
