You are blaming the firefighter for trying to extinguish the fire that was started by the arsonists (Houthi terrorist cult) YET AGAIN when they made a coup back in September 2014 (as I wrote they have waged several wars against the Yemeni state since their foundation in 1994).
That's a tremendously interesting "logic".
Hadi was a transitional figure and made very promising reforms such as making Yemen a federal state.

Also what do you expect? This is the Middle East. You know it is bad (if democracy is the goal) when Israel and Turkey are the supposedly "shinning" lights in the region. Why the double standard? You are calling for democracy in Yemen but why not in Iran? Or real democracy in Pakistan. I mean democracy where the military has no say and does not meddle and where widespread corruption is removed.
Somalia also has democracy on paper yet it remains a failed state. So do most of those Sub-Saharan African states that score the lowest on all categories as well. Zimbabwe is the recent example of this.
Then you have the likes of China, KSA (no direct comparison). Strong authorization states that are far from perfect but where basic services, law and order and progress prevails and reforms take place at the right pace mostly, at least in KSA, not sure about China.
BTW I don't live in the US. Left California (as a student) years ago.
Speaking about the US, until 150 years ago you had millions of slaves, de facto slaves until 60 years ago in the South and racial segregation and what not. 190 years after the foundation of USA. Let us give the modern-day entities in the Middle East 190 more years and then we can talk. Not to forget that the US which is located far away, was never at war in the neighborhood or suffered from invasions, colonialism (post independence) etc. Different story in most of the Muslim world.
