If Jaalle Siad Barre or his successor were in power in the 90's and the country was functioning.
In my opinion I think if he and his army tried to invade Djibouti the West wouldn't intervened.
Because Djibouti is Somali.
Djibouti is a massively important strategic chokepoint.
The West intervened in Kuwait because of the similar geostrategic location and its massive oil/gas reserves.
