The cost of 40,000 foreign advisers during the Shah Pahlavi era was greater than the expenses of the Iranian army. Zakani, Mayor of Tehran: Documents, memoirs, spy books and memoirs of advisers indicate the presence of 40,000 foreign advisers in the country, and the total amount of money they received exceeded the total budget and expenses of the Iranian military. At that time, every person, regardless of their position or rank, was subject to injustice, humiliation and prejudice. The Iranian people celebrate events such as the National Day to Fight Global Arrogance by fighting against this arrogant and oppressive mentality, which seeks to subjugate and enslave peoples and plunder the wealth of countries. The Iranian people witnessed a historic leap with the victory of the Islamic Revolution.
