TEHRAN (IRNA) -- The Islamic Republic of Iran would become a great scientific, economic and political power in the Middle East, Central Asia and the Caucasus in the next 20 years, said a senior military commander here on Saturday afternoon.

Addressing a gathering of pilots and air force commanders of the Islamic Revolution Guards Corps (IRGC), the IRGC's Commander, Major General Yahya Rahim Safavi, said "The U.S. will get nowhere by putting more pressure on Iran."

Noting that Washington's unilateral policy has failed all over the world, the commander noted that the U.S. plans to make a unipolar world and a greater Middle East have been defeated.

Moreover, Safavi added, the U.S. public opinion has been mobilized against Washington's war-mongering policies which have revived bitter memories of the U.S. failed war in Vietnam.

Praising services of the IRGC's air force, the commander said that it was the powerful and strategic defensive arm of Iran. Urging the IRGC's air force commanders to try to make further progress in the future, Safavi said the force "has to move ahead of its time in terms of its military and defensive doctrine."

He also urged the air force to watch every moves of enemies more vigilantly.
