Donald Trump’s recent threats to attack Greenland and Iran, and the kidnapping of Venezuela’s president, Nicolás Maduro, have surprised many observers. Democratic representative Ro Khanna tweeted that Trump had “betrayed his MAGA base” by launching a war of choice for regime change in Venezuela. Former Republican representative Marjorie Taylor Greene expressed similar dismay, stating that threatening war with Iran was “everything we voted against in ‘24.”
While Trump’s bellicosity seems like a reversal from his anti-war campaign rhetoric, history shows that US presidencies evolve. Over the last half-century, the pattern is clear: the more time passes since America’s last disastrous war, and the more presidents use force without costly resistance, the more aggressive they become. Successful wars turn doves into hawks, as seen between Vietnam and Iraq.
Jimmy Carter, the only post-WWII president who never sent troops into combat, was influenced by the Vietnam defeat. Ronald Reagan, despite fierce Cold War rhetoric, was cautious about direct war, preferring brief attacks like the 1983 invasion of Grenada and the 1986 bombing of Libya. George HW Bush grew bolder, invading Panama in 1989 with over three times as many troops as Reagan used in Grenada, setting the stage for the Gulf War.
Trump’s current infatuation with war follows this pattern. After the Iraq war’s failure, he initially avoided major conflicts. But now, with no costly resistance in sight, he is escalating. History suggests such hubris often ends in disaster.
