The Iran war could become a “quagmire” similar to the war in Vietnam for Americans if they decide to put boots on the ground, according to Iranian Deputy Foreign Minister Saeed Khatibzadeh.

“I hope that, you know, wisdom prevails, and, you know, diplomacy prevails,” Khatibzadeh told NBC News’ British broadcasting partner Sky News in an interview in his Tehran office that aired yesterday. On the other side, he said, war can drag them into “a quagmire for them.”

Asked what happens if thousands of U.S. Marines on the way to the Middle East get deployed in Iran, Khatibzadeh replied, “We defend.”

“Even suggesting that a foreign country can put boots on the ground of another country, invade another country, occupy the land of another country, is something very much rogue, very reckless, illegal and against all international law,” he said.

“There is no mandate for Americans to do that. And they are doing this because they are so drunk of power, they think that they can do whatever they want. And this is not the case,” Khatibzadeh added.
