@Newbutoldfather I think Trump's statement on Truth Social on Feb 28 2026, the day the war started, makes it clear that the nuclear threat was one of the main reasons for US choosing to start a war in Iran.
Trump's full statement on Iran attacks
A short time ago, the United States military began major combat operations in Iran. Our objective is to defend the American people by eliminating imminent threats from the Iranian regime. A vicious group of very hard, terrible people. Its menacing activities directly endanger the United States, our troops, our bases overseas, and our allies throughout the world.
For 47 years, the Iranian regime has chanted Death to America and waged an unending campaign of bloodshed and mass murder, targeting the United States, our troops and the innocent people in many, many countries. Among the regime's very first acts was to back a violent takeover of the U.S. Embassy in Tehran, holding dozens of American hostages for 444 days. In 1983, Iran's proxies carried out the marine barracks bombing in Beirut that killed 241 American military personnel.
In 2000, they knew and were probably involved with the attack on the USS Cole. Many died. Iranian forces killed and maimed hundreds of American service members in Iraq. The regime's proxies have continued to launch countless attacks against American forces stationed in the Middle East in recent years, as well as U.S. naval and commercial vessels and international shipping lines. It's been mass terror, and we're not going to put up with it any longer.
From Lebanon to Yemen and Syria to Iraq, the regime has armed, trained and funded terrorist militias that have soaked the earth with blood and guts. And it was Iran's proxy, Hamas, that launched the monstrous Oct. 7 attacks on Israel, slaughtering more than 1,000 innocent people, including 46 Americans, while taking 12 of our citizens hostage. It was brutal, something like the world has never seen before.
Iran is the world's number one state sponsor of terror, and just recently killed tens of thousands of its own citizens on the street as they protested. It has always been the policy of the United States, in particular my administration, that this terrorist regime can never have a nuclear weapon. I'll say it again, they can never have a nuclear weapon. That is why in Operation Midnight Hammer last June, we obliterated the regime's nuclear program at Fordo, Natanz and Isfahan.
After that attack, we warned them never to resume their malicious pursuit of nuclear weapons, and we sought repeatedly to make a deal. We tried. They wanted to do it. They didn't want to do it. Again they wanted to do it. They didn't want to do it. They didn't know what was happening. They just wanted to practice evil. But Iran refused, just as it has for decades and decades.
They've rejected every opportunity to renounce their nuclear ambitions, and we can't take it anymore. Instead, they attempted to rebuild their nuclear program and to continue developing the long range missiles that can now threaten our very good friends and allies in Europe, our troops stationed overseas, and could soon reach the American homeland. Just imagine how emboldened this regime would be if they ever had, and actually were armed with nuclear weapons as a means to deliver their message.
For these reasons, the United States military is undertaking a massive and ongoing operation to prevent this very wicked, radical dictatorship from threatening America and our core national security interests. We're going to destroy their missiles and raze their missile industry to the ground. It will be totally again obliterated. We're going to annihilate their navy. We're going to ensure that the region's terrorist proxies can no longer destabilize the region or the world and attack our forces, and no longer use their IEDs, or roadside bombs as they are sometimes called, to so gravely wound and kill thousands and thousands of people, including many Americans. And we will ensure that Iran does not obtain a nuclear weapon. It's a very simple message. They will never have a nuclear weapon.
To the members of the Islamic Revolutionary Guard, the armed forces and all of the police, I say tonight that you must lay down your weapons and have complete immunity. Or in the alternative, face certain death. So, lay down your arms. You will be treated fairly with total immunity, or you will face certain death.
Finally, to the great proud people of Iran, I say tonight that the hour of your freedom is at hand. Stay sheltered. Don't leave your home. It's very dangerous outside. Bombs will be dropping everywhere. When we are finished, take over your government. It will be yours to take. This will be probably your only chance for generations.
For many years, you have asked for America's help. But you never got it. No president was willing to do what I am willing to do tonight. Now you have a president who is giving you what you want. So let's see how you respond. America is backing you with overwhelming strength and devastating force. Now is the time to seize control of your destiny, and to unleash the prosperous and glorious future that is close within your reach. This is the moment for action. Do not let it pass.
