The U.S.–Israel war against Iran illustrates modern politics through a blend of military action, economic warfare, and domestic strain. Israel is targeting Iran’s energy infrastructure to weaken the regime, while the U.S., led by Marco Rubio, aims to cripple Iran’s military without a full ground invasion despite a large troop buildup. Donald Trump has alternated between de-escalation and threats to destroy Iran’s oil sector, underscoring the strategic role of energy. Iran’s retaliation and disruption of the Strait of Hormuz have driven global economic shocks, raising oil and fertilizer prices and increasing recession risks. Meanwhile, civilian casualty controversies, rising U.S. war costs, and domestic political divisions highlight how modern conflicts are tightly linked to internal governance and economic stability.
