Yemen is not that simple boys - it has a lot of tribes and they all like to get involved - bit like Afghanistan
Can't see the southerners (ie Aden area) being very happy about this lot from the far north - and the Saudis still pull a lot of strings in the country
best to stay out of it - they are quite happy fighting each other
The average Yemeni makes the NRA in the States look like Sunday School teachers so there's no need to provide any support to any side
