Ayatollah Khamenei stated that Iran started its nuclear program, because according to experts' estimates, the country needed to generate at least 20,000 megawatts of nuclear power, but the United States opposes Iran's nuclear program as it is basically opposed to scientific progress of the Iranian nation and other nations.
As regards the best approach to deal with the enemy's hostile moves, Ayatollah Khamenei said Iranian authorities should prove it to the "corrupt leaders of the U.S. regime" that they rely on the Iranian nation who would never bow to force.
Supreme Leader of the Islamic Revolution and Commander-in-Chief of the Armed Forces Ayatollah Seyed Ali Khamenei on Sunday warned that "any wrong doing in connection with the nuclear deal will spark reaction of the Islamic Republic of Iran", IRNA reported.
The Leader of the Revolution went on to say: Today we witness, despite all the contracts, deals, and multiple talks regarding the JCPOA, the attitudes of the United States towards the negotiations and their outcomes are totally oppressive, hounding, and cruel.
On regional issues, he noted that the reasons behind insecurity in the Middle East can be traced to the "wicked and mischievous interventions" by the US.
"The Iranian regime stands firm", Khamenei stressed.
His comments came after U.S. President Donald Trump said on Thursday that Iran was violating "the spirit" of the 2015 deal under which Tehran got sanctions relief in return for curbing its nuclear programme.
"Today, there is a consensus in the world that the JCPOA (or Iran's nuclear deal) benefits security, stability and development in the region and the world", he was quoted as saying by Press TV.
"Iran also expects the European Union to send this strong message to the US (administration)", Rouhani said during a meeting with the visiting president of the Chamber of Representatives of Belgium, Siegfried Baracke.
The global agreement is facing a serious threat of collapse as tensions mounted between Washington and Tehran recently.
