Which is a sane and balanced opinion. The Houthi's are a terror cult though and do by no means represent the Zaydi community of Yemen which traditionally always had close and cordial ties with KSA. Look no further back than to the Yemeni civil war of the 1960's and in more recent times. Also the Zaydi's are very close to Sunnis, especially of the Hanafi and Shafi'i fiqh. There is even a sizable Zaydi community within KSA.
This has little to do with a Sunni-Shia conflict. It's more an internal Yemeni struggle that outsiders (a certain Mullah regime) try to hijack. It's bound in the North/South divide in Yemen, bad policy of all parties involved and most importantly Ali Abdullah Saleh and his gang. Read up on him and his son. It's basically a power struggle and the Houthi's are used as cannon fodder by Saleh. The opposition which has the vast majority of the support in Yemen has to unite and form a common ground. Opposition political parties, Southern separatists, Northern separatists, Southern Communists, Islamists, nationalists have to find a common ground. A bunch of rednecks and a cult (Houthi's) cannot rule an ancient country like Yemen regardless of Yemen being full of problems for a long time now. Just take a look at their leaders and spokesmen. They are high on qat 24/7 and making silly speeches and threats while they are bombed back to a pre-historic age.
Yemen deserves better and will get better.
