So here's a fun bit of geopolitical time travel. President Donald Trump decided to dust off some 37-year-old foreign policy commentary this week, sharing a clip from a 1987 interview where he proposed a rather straightforward solution to Iranian aggression: take their oil.

On Monday, Trump posted a snippet to Truth Social from his 1987 sit-down with the late Barbara Walters on ABC's 20/20. The interview happened during the Iran-Iraq War, a few years after the whole hostage crisis drama. A younger Trump, looking characteristically unimpressed with American foreign policy, laid out his thinking. If Iran attacked the U.S., he argued, Washington shouldn't just retaliate—it should go shopping. Specifically, for oil infrastructure.

"Grab one of their big oil installations," Trump suggested, "and keep it." He doubled down for emphasis: "And I mean grab it and keep it." The idea, in his view, was to offset any American losses directly. It's the foreign policy equivalent of making the other guy pay for dinner after he started the fight.

This wasn't even his first rodeo with the topic. In a separate 1980 interview with TV host Rona Barrett, Trump expressed his "horror" that the U.S. allowed Iran to hold American hostages after the 1979 Islamic Revolution. He signaled clear support back then for sending in U.S. troops to get them back. So the theme of a muscular, transactional response to Iran has been playing on a loop in his mind for over four decades.

Why dig this up now? Well, timing is everything. The comments have resurfaced just as tensions between the U.S., Israel, and Iran are hitting new highs, making Trump's old "grab the oil" idea sound less like a historical footnote and more like a potential policy preview.

In fact, Trump gave the concept a fresh coat of paint in a recent interview with the Financial Times, stating his preference to "take the oil in Iran." He followed that up later the same day with a more specific threat: if the Strait of Hormuz isn't reopened immediately, he'd destroy Iran's oil infrastructure—wells, power plants, and crucially, Kharg Island.

Ah, Kharg Island. That's the important bit for anyone watching the markets. It's not just any piece of real estate; it's Iran's main terminal for exporting crude oil. Mentioning it by name is like pointing a spotlight at the jugular of Iran's economy and, by extension, a nerve center for global energy supplies.

And the markets noticed. These threats coincided with West Texas Intermediate (WTI) crude oil prices surging to $102.81 a barrel. That was up a modest 0.06% on the day, but more strikingly, it represented a gain of over 40% for the month. When a leading presidential candidate starts talking about seizing or destroying major oil assets in a volatile region, traders tend to price in a little extra risk premium. It's a classic case of geopolitical rhetoric becoming a tangible market force.

So what we have here is a blend of past and present. A consistent, decades-old worldview from Trump—one that favors dramatic, asset-based retaliation—is being reintroduced into a current climate where such actions are suddenly within the realm of political discourse. For investors, it's a reminder that election years aren't just about domestic policy; they're also about the resurrection of old ideas that can move commodity markets in real time. The 1987 interview might be archived footage, but its underlying philosophy is very much part of the 2024 conversation.
