Why Is the US Aligned With Saudi Arabia?

When I watch the news  these days, I believe that media is  always mentions one part more than the other for many reasons. Politics controls everything that we get directly or indirectly. After I read an article talks about “Why Is the US Aligned With Saudi Arabia?” which explains the relationship between USA government and Saudi Arabia rulers like  “oil men to oil men” that proves to me why the US government could not really do anything about the situation  in Yemen. The Saudis are fighting Yemeni because they are worried that the Houthis, who rose up in Yemen, are close to Iran. Many of the conflicts plaguing the Middle East today have been exacerbated by the Saudi-Iran enmity. Saudi leaders see Iran’s policies as part of an expansionist, sectarian agenda aimed at empowering Shia Muslims in the region at the expense of Sunnis. Iranian leaders attribute similarly sectarian motives to their Saudi counterparts. If Saudi Arabia was not favored to USA government, it will not keep the war years without finding a better solution.
