Her'es the first couple on my list:
I'd support a coup in Singapore or Saudi Arabia. I never hear anything about Brunei, so I'm not too familiar with them.
Brunei is a small contry on an island that also contains parts of Indonesia and Malaysia. The ruler of Brunei is a sultan who's a huge mysognisitic asshole. He has a huge number of concubines, many of whom were kidnapped and forced into that, and has actually been known to use front groups such as talent agencies to lure women from countries like Japan and the US over where he uses them as sex slaves. There's a lawsuit from an American woman against his brother over this, she tried to sue him himself but apparentely you can't sue heads of state. BS. The man is pure scum and needs to be taken out. And to top it all off it has ultra-right wing neoliberal economics similar to Singapore.
