Imam frequently used to condemn those powers that developed chemical or nuclear weapons for military or war purposes and were proliferating around the world.
Imam expressed on several occasions that the chemical or nuclear weapons have had no place in the Islamic Republic's policy and strategy.
The founder of the Islamic Republic also had forbidden development of any weapons that could harm the humanity on a large scale during peace or war.
The great leader also denounced the imperialistic powers of arming former Iraqi dictator Saddam Hussein with chemical weapons who used these weapons of mass destruction against its own people and the Iranian nation.
After Saddam's attack on Iran on America's instigation Imam asserted that:
"We always make it a point that our response to their attacks should be such that the Iraqi people are not harmed. But in case Iraq oversteps its limits and repeats its aggression, we are resolved and determined to mobilize the people and order them to fight. It will then become clear to the Iraqi people that we have nothing against them and that it is this Saddam Hussein who has attacked us on America's instigation. Our response to his attack will have nothing at all to do with the people of Iraq who are our brothers."
(Sahifeh-ye Imam, vol. 13, p. 193)
The Islamic Republic under the wise leadership of the great Imam joined all agreements and treaties that restrict or ban the development or use of such type of arms and weapons.
Imam was pursuing a world free of nuclear arms or the weapons of mass destruction.
The great intellectual and scholar also slammed Israeli regime for developing hundreds of nuclear warheads and posing a great danger to the region. He believed in disarmament of all so-called superpowers and opposed double standard being practiced regarding these type of treaties on the international stage.
Imam maintained that the only way out of regional and international crisis were to hold peace negotiations and dialogue among civilizations. He was against warmongering policies and aggressions being practiced by the colonial powers.
Imam declared that the nations should be given chance to determine their own future and destinies.
He undertook very hard struggle to eradicate poverty and inequality from around the whole world. He was staunch supporter of oppressed people and nations and raised awareness against cruelty and oppression.
