Young man, Iran said they were at war with us since 1979. Are you a Zionist?
In summary, Iran has indeed indicated that it views its relationship with the United States as one of conflict since 1979, stemming from the events of the Islamic Revolution and the subsequent hostage crisis
Pres. Donald Trump very consistently labeled Iran a threat during his first administration. He described it as the “dominant Islamic power in the Middle East and on the road to nuclear weapons” and asserted it posed a risk of “nuclear holocaust.” His administration implemented a “maximum pressure” campaign (ie., economic warfare) involving over 1,500(!) sanctions, increased cooperation with regional allies, and withdrew from the JCPOA to counter Iran.
Additionally (you have to be dishonest to “forget” this one), Trump authorized multiple military strikes against Iranian-backed proxy groups during his first administration, marking a significant escalation from previous U.S. policy.
