Which middle east country was only country accepted the communist but western-educated shah (ruler) Reza phalevi resisted the Russian and signed a defense treaty with USA in 1950?

Answer 1

The country you are referring to is Iran. Reza Shah Pahlavi, who ruled Iran, was a secular and modernizing leader who sought to limit the influence of communism in the country. Despite some communist influence, especially with the Tudeh Party, Reza Shah resisted Soviet expansion and sought to strengthen relations with the West, culminating in the 1950 defense treaty with the United States.
