Interventionism is the root of most suffering in Human History. There is no moral reason to Influence another countries affairs or cultures.
Interventionism is the cause of Imperialism, Expansionism, Power Projection and all religious Wars. Every one of these things were driven by the thought that your society or way of living has a moral high ground or is more civilised. There is no good in trying to "fix" another country or culture. We would be better off if every country just looked after itself. I don't mean "Don't start wars", that wouldn't be an unpopular opinion. Don't try to change another country or culture, even if it is completely polar to your values. Western countries should not intervene in the middle east. Fundamental Muslims should not try to instate sharia law in secular societies. We shouldn't care if china is authoritarian. We shouldn't care how el salvador treats its criminals. As long as it doesn't concern your Country (Climate, health, direct military threat) you should leave it be. No one culture has a definite moral high ground over another.
(Ive marked this as political because it doesn't directly have something to do with the middle east)
EDIT: Since someone has pointed out a flaw in my logic, I will edit parts of my statement:
I believe that while some cultures are morally superior over others, imposing their beliefs onto other, even morally inferior cultures is in practicality wrong and harmful.
