The President continued: "Everybody must pay attention to the fact that achieving our favourable authority is legitimate power and fruitful for our society".
"The Iranian nation has the required technical and legal logic for negotiation with powers and promoting its rights," he added.

He went on to say: "We will not ask for permission four our brave, scientist young people's research but we are ready for constructive interaction".

Dr Rouhani added: "We need military and defence power, economic power and cultural power simultaneously for legitimate authority in the region and the world".
Stating that "we stood on our feet in hard days, and we know that the enemies are not happy with our progress", he continued: "We have never looked for the satisfaction of our enemies; first, we want satisfaction from God and our people".
The President also went on to say: "Over the past few years, we have defeated the enemies in their goal of using terrorist as a tool against the region".
"Along with the power of science and technology, we need the power of diplomacy to promote the rights of our nation," he added.
Dr Rouhani continued: "We cooperate with Russia, China and European countries in the field of nuclear research and development".

Emphasising that "we proved to the world that we live up to our commitments", he continued: "Many tried to make us destroy the JCPOA with our own hands, but they failed against our nation's intelligence".
"In the end, it is YOU who must pay the price of killing the JCPOA, not the Iranian nation," added the President, saying: "They have spent billions of dollars to bring down the JCPOA building, but it still remains to this day".
Dr Rouhani continued: "Whether JCPOA stands or not, with the US or without it, we are ready for any situation and have plans for it".
Stating that "if they hurt the JCPOA one day, they will lose their reputation in the world", he added: "The Iranian nation cannot be derailed from independence, freedom and the causes of the Revolution with propaganda".

He continued: "Our weapons are defensive and the guarantor of peace in the region," adding: "We will develop any weapon to defend our nation".
"The base of our relations with neighbours is development of peace and friendly cooperation; those who say incorrect words and the newcomers in the region will understand this," he added.
