In my campaign Carthage always conquers Syracuse

In general those small nations like Syracuse are crucial for easy victory over Carthage, without my intervention, Carthage took over or subdued entire western Africa, took 1/2 of Spain and entire Sicily after long fight with Syracuse. At that point I made friends all over the world, then I used tchem to take down Carthade slowly, Ptolemaioi occupied their African armies, Iberians were slowly taking their lands back and I landed in Africa, taking down Maesyli. Later with few big attack I took their islands and Carthage itself was cunquered around 130 turn.
