The reality of power is morally ugly, necessitating strategic alliances with monstrous figures, like the US partnering with Stalin to defeat Hitler. This isn't an aberration but a core function of geopolitics: using a lesser evil to combat a greater, more immediate threat.

The Romans often propagandized the concept of 'Punica Fides' or 'Punic Faith' to portray Carthaginians as uniquely treacherous. Yet, their greatest general, Scipio, used blatant deception by feigning peace negotiations with Sifax and Hasdrubal specifically to learn the layout of their camps before burning them down, highlighting the hypocrisy of wartime rhetoric.

Italian leaders openly framed their switch of alliances as a "sacred egoism" – a divinely appointed mission to enlarge the fatherland. This concept sacralized raw national self-interest, providing a moral justification for betraying former allies and pursuing a war of conquest.

While most WWI belligerents framed their involvement as a defensive necessity for "Hearth and Home," Italy was transparently opportunistic. Its leaders openly admitted they were not defending themselves but attacking for conquest and glory, making it arguably the most acquisitive campaign of the war.

Lacking a parliamentary majority for war, Prime Minister Salandra executed a masterful political maneuver by resigning. This dared the king to appoint an anti-war successor amidst orchestrated street protests. Fearing civil unrest, the king was forced to reappoint Salandra, effectively greenlighting Italy's entry into the war.

Despite widespread public opposition, the Italian government used celebrity poet Gabriele D'Annunzio to ignite war fever. His impassioned, quasi-religious speeches created a frenzy among a vocal urban minority, pressuring politicians and the king into a war the majority of the population did not want.

The harsh terms of the First Punic War, which stripped Carthage of territory and imposed a massive indemnity, created deep resentment. This parallels the Treaty of Versailles with Germany, illustrating how overly punitive settlements can sow the seeds of a future war of revenge rather than secure lasting peace.

Italy joined WWI after being promised vast territories, but received only a fraction of them after immense sacrifice. This widespread sense of betrayal and resentment over a "mutilated victory" created the perfect political environment for nationalists like Benito Mussolini to rise to power in the 1920s.

As a newly unified country, Italy lacked a strong national identity. Leaders cultivated a sense of grievance and "unfinished business" over its border with Austria, a concept known as irredentism. This became a powerful political tool to weld the new nation together against a common enemy.
