Iranian President Hassan Rouhani is adamant his country is no threat to the rest of the world.
At the UN General Assembly's annual meeting at their headquarters in New York, Mr Rouhani insisted Iran poses "absolutely no threat to the world or region" and called on the West to treat Iran as a more equal partner.
Mr Rouhani declared the world is tired of war, calling on the world to "reject violence and extremism".
He also called on Barack Obama to ignore "warmongering pressure groups" and move for a better relationship between the two nations, despite criticising the country's handling of the Syrian crisis and the country's use of drones.
His speech comes ahead of renewed negotiations over Tehran's nuclear programme, over which President Obama has declared the UN "should be able to achieve a resolution."
The UN Security Council has imposed four rounds of sanctions against Iran over its uranium enrichment, which Mr Rouhani says is an unrealistic way of trying to ensure a peaceful solution to the issue.
Israeli Prime Minister Benjamin Netanyahu has said that President Rouhani's UN address was "cynical" and Tehran was stalling for time in order to develop nuclear arms.
"It was a cynical speech full of hypocrisy," Mr Netanyahu said in a statement after Rouhani addressed the annual gathering of world leaders at the United Nations General Assembly.
"It had no practical suggestion to stop Iran's military nuclear programme and no commitment to fulfil UN Security Council decisions. That exactly is the Iranian plan, to talk and buy time in order to advance Iran's capability to obtain nuclear weapons."
Mr Netanyahu said he would welcome a diplomatic solution that dismantled Iran's capacity to develop nuclear arms, but that Israel "will not be fooled by half-measures that merely provide a smokescreen for Iran's continual pursuit of nuclear weapons and the world should not be fooled either".
