Even before this attack by the Saudis, look at its involvement and the kind of manipulation and control and creation of a system far from providing equality for all as could THIS from Wikipedia suggests:

"In the absence of strong state institutions, elite politics in Yemen constituted a de facto form of collaborative governance, where competing tribal, regional, religious and political interests agreed to hold themselves in check through tacit acceptance of the balance it produced.^[15] The informal political settlement was held together by a power-sharing deal between three men: president Ali Abdullah Saleh, who controlled the state; major general Ali Mohsen al-Ahmar, who controlled the largest share of the army; and sheikh Abdullah al-Ahmar, figurehead of the Islamist Islah party and Saudi Arabia's chosen broker of transnational patronage payments to various political players,^[16] including tribalsheikhs.^{[17][18][19][20]} The Saudi payments have been intended to facilitate the tribes autonomy from the Yemeni government and to give the Saudi government a mechanism with which to weigh in on Yemen's political decision making.^[21]

... Saudi Arabia's main concern was to maintain its influence in Yemen through some old regime figures and other tribal leaders who were part of the so-called "GCC initiative""

Remember, the actions and intentions mentioned here are not related to some democratic country that is also not known for targeting a specific group. On the contrary, this is a report suggesting talking and walking like a duck related to what we already know as a duck. 

And for the guy who describe himself as the legitimate president, HERE is how he was elected according to wikipedia
