Saudi Arabia has been criticized by civilians, due to abuse of human rights.
But, officially, almost all of the nations worldwide don't refer to it, because they want to be in good terms with Saudi Arabia, which is an ally of the United States. Though Saudi Arabia is losing its portion as an oil-dependent country after US's sudden increase of oil production, the country is still important for most of the countries around the world for importing oil. It means it's difficult for them to resist Saudi Arabia, even if the authority of the nation takes unhumanitarian measures.
So far, United States is the only country that can scold the Arabian country, even if the nation declares suspension of exporting oil.
So, President Trump should deal with the issue with decent attitude.
