The United States has grown weaker day by day throughout the past 20 years when it comes to its domestic and external policies, economy, and security, Iranian leader Ali Khamenei said on Tuesday.

"The world is before a new world order that is not bipolar, and Iran and the rest of the world should take part in it physically and systemically," Sayyed Khamenei told university students in Tehran.

On the occasion of the upcoming Al-Quds day, he touched on the Palestinian cause, saying the Islamic governments in the world were doing "a bad job toward Palestine, and some of them are not ready to talk appropriately about it."

"A major mistake is thinking that communication with the Zionists is the most appropriate manner to help Palestine," he added, noting that their crimes have been the same for the past four decades.

On the occasion of Al-Quds day, resistance figures from West Asia delivered addresses to voice their unequivocal support for occupied Palestine and its occupied capital, Al-Quds, against the Israeli occupation and its malicious plans for the country.
