I mean even with that size they got two big powerful countries right next to them, just like Qatar they cant defend themselves and they got tons of resources, cant blame them
The RAF could have simply just bombed the Ikhwan, which they very sucsesfully did to rout them when they tried to conquer Jordan (which was actually very close to happening- they were a few miles outside of Amman).
Also the Ikhwan did not even try to conquer Kuwait they just raided it's border towns and the English just balkanized them for that. Also they did not even invite Kuwait to the treaty they straight up had no say, kinda sad.
