The appointment of Mojtaba Khamenei as the new Supreme Leader of Iran has drawn reactions from United States. According to US media reports, Donald Trump is unhappy with the selection and had earlier warned that Iran's next leader would "not last long" without American approval. However, no formal statement has yet been issued by the White House. Mojtaba's elevation is seen as consolidating hardline control in Tehran and could further escalate tensions with Israel and Washington amid the ongoing regional conflict.
