RNA - "We must be strong and powerful, because the Qur'an tells us that we must be so powerful to take away the courage from the enemy and those threatening us," he told the inauguration of a defense museum in Tehran Sunday.
"This means the enemy has either to be made disappointed about achieving a success or know that if it attacks us, it will have to pay immense costs," the president added.
Iran's defense capabilities have become the subject of US interest for fresh pressures on Tehran, especially the country's missile program.
On Monday, US Ambassador to the United Nations Nikki Haley said Washington was encouraging other UN Security Council countries to set aside the nuclear deal with Iran loathed by President Donald Trump and focus on cracking down on Iran’s missile program.
Rouhani said Iran's defense power is a deterrent, over which the country will never negotiate in the face of threats.
"Our national power is for peace, we gain power for deterrence. Deterrence is the same as dignified peace. We should be ready to remove and thwart threats against the people," he said.
Rouhani said Iran was ready to answer any possible questions but stressed that the country would not negotiate about its defense capabilities.
"Our nation and authorities do not and will not need to negotiate with anyone or reach a deal with any power over their defensive capabilities," he said.
"If any authority comes and asks a question, we will give a firm and strong answer. Our answer is clear. But we will procure any weapon or capability which we need within the framework of rules and regulations and the fatwas of our Leader," he added.
Rouhani reiterated that the Islamic Republic is not after weapons of mass destruction according to a fatwa by Leader of the Islamic Revolution Ayatollah Seyyed Ali Khamenei.
The president further touched on US threats against Russia with new atomic weapons following Washington's publication of a document outlining plans to expand its nuclear capabilities.
"You see how the Americans are shamelessly threatening Russia with a new atomic weapon," Rouhani said.
"The same people, who believe that weapons of mass destruction are a crime against humanity and say that international bodies have condemned them and all should destroy them, talk about new weapons," he added.
The US military has put countering China and Russia, dubbed "revisionist powers", at the center of a new national defense strategy unveiled earlier this month. US officials say by expanding its own low-yield nuclear capability, the US would deter Russia from using nuclear weapons.
Rouhan said Iran manufactures most of its weapons and military equipment.
Touching on the Iraqi-imposed war on Iran in the 1980s, Rouhani noted that the Iranian people and clerics stood up against an intruding army while neither the UN nor the regional states and friendly countries defended their land.
During the wartime, he said, Iranians put their trust in high-ranking military and political officials while world powers and reactionary regional countries supported the former Iraqi dictator Saddam Hussein.
