President Donald Trump has privately expressed serious interest in deploying U.S. troops on the ground inside of Iran, according to two U.S. officials, a former U.S. official and another person with knowledge of the conversations.

Trump has discussed the idea of deploying ground troops with aides and Republican officials outside the White House while outlining his vision for a post-war Iran in which Iran’s uranium is secure and the U.S. and a new Iranian regime cooperate on oil production similar to how the U.S. and Venezuela are, the sources said.
