A good strategist will assess the strength of an opponent and adopt a security posture that is not only meant to fight the enemy but to scare them from such an undertaking. Buying high sophisticated jet fighters and bombers may be an important deterrence for Uganda. For instance Khartoums [Sudan] or Egypt's assessment of Ugandas military preparedness and capacity will determine their method of attack or cooperation: If they smell weakness, they may fight directly; if they think Uganda UPDF is strong, they may chill.....Used MiG-29SMT would be better. But also overkill.
To be honest I'm not sure they need fighter aircraft at all.
