Again, the Saudi government has no right to conduct its attacks in Yemen and its actions are not even anywhere close to being justified as self defense and it is itself one of the worst dictatorships on earth and therefore is not expected to bring the goodness of democracy there. Instead, what we find is a dirty discrimination and singling out for one group to attack wherever it can reach them.

So why the world is tolerating the Saudi government action in Yemen and why this president is also supporting and backing it? 

The dirtiness of a nation conspiring on its own minority

Although I feel confident about my theory that the Saudi government conspires with ISIS (ISIS not AlQaeda) when I saw THIS I still wanted to subject that theory to the scrutiny called for by that. It however did not take me more than to reach the end of that news page to see how things can fit with my theory and the Saudi government in even dirtier role. It seems like the Saudi government wanted to hit two birds with one stone by letting ISIS attack its minority Shia to strengthen the perception that it is on the opposing side to ISIS then came to the realization of how that could actually give more reason for suspicion so it used this one to balance things out. 

I haven't seen somebody attacking another person while acting as if the attack is directed toward different entity like the Saudis have been doing in Yemen and claiming Iran as being the reason except in exorcism.

Things in THIS site suggest that the Saudis are causing humanitarian crises and sever shortage of food in Yemen.

Who is for democracy (real not fake) in Yemen?

Why would people agreeing on the same thing be fighting? If those rebels in Yemen want a system of real democracy and equal voting rights for everybody and are seeking power in order to secure being treated equally then they need to convey that message more clearly to the world.

Fighting has been going on for so long and we still don't know who is with a system of one person one vote and who is not? If you don't trust that the other side would really implements such system then don't express that as a stand against democracy and instead ask the world for answers to such fears if they don't want you in power. 

The White House sends condolences to China for the death of people but those Shia in Iraq being killed even for just today in bigger number than that, apparently accepted as part of normal life.

You know why the Shia being attacked like this? Because probably earth did not know another group as morally restricted from making a generalized response that could unjustly include the innocent Ssunnies as they are (however again, if a level of justice like in this country is the line they do not want to cross I am not sure they are working sufficiently within this line to prevent such attacks).     

Like I said previously, attacks and death of the Shia in Iraq are tolerated as normal part of life that they are, and have been so for a long time, hardly given attention by the news media. Today I did a search to demonstrate that and HERE is an example of what I found. Here is ANOTHER  example. And here is a THIRD one. Here is a  FORTH  one. 

While there is no excuse in targeting the innocent for the action of the guilty, one would still wonder if history had known any other example of a majority in the position of power controlling themselves from unjust and generalized responses like the Shia in Iraq? 

However, while I may complement self restrictions not to violate justice I still criticize hardly the lack of sufficient work with in the lines of it.

By the way, the attacks in Ssunny cities are conducted by the same groups and generally target government forces.
