US President Donald Trump on Saturday said  Iran is developing long-range missiles capable of threatening Europe, US troops abroad, and potentially the American homeland.

Posting on Truth Social, Trump said Iran “attempted to rebuild their nuclear program and to continue developing long range missiles that can now threaten our very good friends and allies in Europe, our troops stationed overseas and could seen reach the American homeland.”

He added that the US is conducting a “massive” operation to “prevent this very wicked radical dictatorship from threatening America.”

Trump also said the US has not made any “final decision” on striking Iran, expressing his dissatisfaction with Tehran’s stance in ongoing nuclear negotiations.

He said Iran was “not willing to give us what we have to have,” stressing that Iran “cannot have nuclear weapons.”

Indirect talks between the two countries were held earlier this week in Geneva, with both sides reporting progress toward a possible agreement.

Trump reiterated that Washington is “ready, willing, and able” to act “with speed and violence, if necessary,” while acknowledging the risk of an extended conflict in the Middle East. “When there’s war, there’s a risk of anything – both good and bad,” he said.
