Who bears primary responsibility for U.S.–Iran tensions: the United States or Iran?

Welcome to the debate arena! Today's topic: "Who bears primary responsibility for U.S.–Iran tensions: the United States or Iran?". Your opponent's style: Iran Supporter

The U.S.–Iran conflict is one of the most enduring and complex rivalries in modern geopolitics. Since the 1979 Iranian Revolution, relations have been hostile, shaped by disputes over nuclear ambitions, sanctions, proxy wars, and military interventions. The situation escalated sharply in 2018 when the U.S. withdrew from the nuclear deal, and most recently in 2026, when U.S.–Israel strikes killed Iran’s Supreme Leader, triggering open war. But the US is not the one to be blamed here. Wasn't it Iran who consistently continued uranium enrichment despite global warnings and kept threatening the US and it's allies? Iran’s nuclear defiance undermined trust even before US broke the nuclear deal

Wrong frame entirely. Iran enriched uranium on *its own soil* for *its own energy*—that's not defiance, that's sovereignty. The U.S. demands Iran surrender nuclear capability while Israel sits on 90 warheads untouched. Pure double standard. You say Iran "threatened" first? The U.S. overthrew Iran's elected PM in 1953, imposed crippling sanctions, and withdrew from a deal *Iran was honoring*. Then Trump assassinated Soleimani, and now the Supreme Leader. You're blaming the person getting punched for bleeding on your fist. Iran didn't start this war—decades of American pressure and humiliation did. Stop pretending defense is aggression.

"Defense is aggression" you say? So you mean to say that those attacks on Oil Tankers in the Gulf, the Houthis in Yemen and Militias in Iraq and Syria were defense mechanisms? Last I checked, Iran was the first to strike. The US and other allies are not to blame for Iran's stubborn decisions despite international warnings to not do so. Even the dictionary would be ashamed of how you foolishly compare aggression to an act of protection for your nation

You're cherry-picking attacks while ignoring who threw the first punch historically. The U.S. imposed sanctions that strangled Iran's economy, assassinated its generals, and backed proxy wars against it for decades. Iran's regional activities? Response to encirclement, not unprovoked aggression. And "international warnings"—you mean U.S. demands backed by threats. The nuclear deal *was* Iran complying with international consensus. Then America tore it up unilaterally. Of course Iran escalated after that betrayal. You want to play "who struck first?" Start with 1953. The U.S. created this enemy, then acts shocked when it fights back. Stop rewinding history to whenever suits your argument and owns the full timeline.
