DAMASCUS - Syrian President Bashar Assad welcomed Iranian President Mahmoud Ahmadinejad to Damascus on Wednesday.
At a joint press conference, Ahmadinejad spoke of a new Middle East void of Zionists.
"If the Zionist regime [Israel] wants to repeat its past mistakes, this will bring about its demise and annihilation," he said.
"No one can damage" the close bond between Iran and Syria, Ahmadinejad told reporters. "These ties will become deeper and develop over the years."
"We are brothers. We have mutual interests, as well as common goals and enemies," Ahmadinejad said.
"The Zionists and their protectors have reached a dead end. The Zionist entity will eventually disappear," he said in what has become his mantra on the demise of the Jewish state.
"Its existential philosophy has ended. The Zionist conquerors have reached a dead end. All of their threats against the Palestinians stem from their weakness. If the Zionists repeat their past mistakes, all of the region's nations will uproot them," he said.
"With Allah's help, the new Middle East will be a Middle East without Zionists and imperialists. We hope they will recognize the rights of the region's nations, but they must realize that if they continue along their wrongful path, they have no place in our region," Ahmadinejad said.
"Today, the ties between the region's nations - between Iran, Syria and the resistance movement [terror groups] - are very strong. We believe that developments in the world will benefit Iran, Syria and the region's free governments," he said.
Ahmadinejad advised the U.S. to "pack their things and leave" the region.
"[The Americans] want to dominate the region, but they feel that Iran and Syria are preventing that," he said. "We tell them that instead of interfering in the region's affairs to pack their things and leave," he said.
Assad, for his part, claimed Israel is preparing for war.
"We believe we are facing an entity that is capable of aggression at any point, and we are preparing ourselves for any Israeli aggression, be it small or large scale," the Syrian president said.
"We must be prepared for any Israeli response, under any pretext," he said.
"Israel is directing its threats at Syria and the resistance movements. The threats are also aimed at boosting the Israeli citizens' morale after a series of defeats," Assad said.
On Wednesday, U.S. Secretary of State Hillary Clinton told congressmen that the Obama administration's decision to reinstate an ambassador to Syria was not without concerns for Syria's close relationship with Iran and its support of terror groups.
