President Donald Trump struck a defiant tone amid the rising prices, saying that a gain in "short-term oil prices" was a "very small price to pay" for destroying Iran's nuclear threat."Only fools would think differently!" Trump added.During the briefing, the South Korean president said the crisis in the Middle East had placed a "significant burden" on his country's economy, which is heavily dependent on trade and energy imports from that region.
