An Iranian government official has stated to CNN that the United States should be held directly responsible for the ongoing conflict and "pay the price." The official added that Iran anticipates the war lasting up to two years and has completed necessary preparations. While the official didn't elaborate on the specifics of Iran's preparations, this statement signals a potential escalation of tensions in the region. The assertion of US responsibility likely stems from Washington's support for Israel. The claim of a two-year timeframe suggests a long-term strategy and willingness to engage in a protracted conflict. Further developments are expected. ```
