Iranian President Hassan Rouhani warned on Friday that his country  will “resist” the United States officially recognizing this week Israel’s sovereignty over the Golan Heights.

The Iranian president said U.S. President Donald Trump’s declaration this week is “trampling on international regulations about the Golan.”

Rouhani said Iranians “should resist, and that way gain victory” over America and Israel.

Israeli Prime Minister Benjamin Netanyahu, who stood by Trump’s side at the White House on Monday, called the decision a “historic justice” and a “diplomatic victory.”

“Israel won the Golan Heights in a just war of defense,” he added, referring to the 1967 Six-Day War and Israel’s control of the Golan Heights since then.
