In recent days, President Donald Trump has voiced mixed messages about how the White House may address oil prices and related cost woes.
Trump has indicated the war may end soon, but he has also threatened to escalate the conflict if Iran continues to impede tanker traffic in the Strait of Hormuz.
In a social media post on Thursday morning, Trump downplayed the rising oil prices, saying they would financially benefit the U.S.
“The United States is the largest Oil Producer in the World, by far, so when oil prices go up, we make a lot of money. BUT, of far greater interest and importance to me, as President, is stoping an evil Empire, Iran, from having Nuclear Weapons, and destroying the Middle East and, indeed, the World,” Trump said.
In his first purported message, Mojtaba Khamenei, the newly installed supreme leader of Iran, on Thursday addressed the importance of the Strait of Hormuz.
Khamenei said the closure of the shipping route must be sustained as a “tool to pressure the enemy,” according to CNBC.
