Why does no Western power intervene in Yemen like they do everywhere else?

You're lucky if you're news channel is mentioning Yemen, let alone discussing it. One of the poorest Arab countries adjacent to one of the richest Arab countries.

Yemen is strategically important because of it geographical location. A couple of years ago the Houthis were gaining power, but they are not allies of the west, so the US and its allies decided to put a stop to that by supplying arms to Saudi Arabia to destroy Yemen and put in a government that supports the oil business of the west. 

It is all about politics and getting a pro-western government in power, no matter how many innocent people are killed. 

They are !!  Britain has supplied 10 billion worth of arms in the last few years to Saudi Arabia the USA more , yemen is having a civil war  where like Syria rebels are trying to take over but the west wants to stop them so get Saudi Arabia to do their dirty work , like they did with Sadam Hussein and Iran then killed him as you do , and our arms manufacturers make billions killing kids in Yemem our celebraties  ask for charity to help the people and kids as you do in a manic society led by money 

We are intervening, on the side of the Saudi's

They have been fighting a proxy war.  The West is funding Saudi Arabia to support the government.  Russia is funding Iran to support the rebels.

Saudi Arabia tells them not to, and too many Western countries bow to the Saudis, so they can literally get away with murder

I studied in Yemen.  It was a nice place before people like the Saudis and Mr Obama started shooting and bombing the place up.
