On the 18th local time, US Secretary of State Blinken said at a press conference at the UN headquarters in New York that after nearly 30 years of efforts, the US government's "regime change experiment" in Iran has not achieved the expected success. Blinken believes that the pressure and sanctions imposed by the United States on Iran in the past 20 years have not changed the core values and policy direction of the Iranian regime.

However, Blinken also stressed that the United States will continue to support democratic processes in the Middle East and work with allies to combat terrorism and other forms of threat. In addition, he also mentioned that the United States is engaged in dialogue with other countries to seek common interests and solutions.

Mr. Blinken's comments, however, drew widespread international attention, with some observers pointing out that such a statement by the United States could affect its relations in the Middle East and could lead to more uncertainty. They also fear that if the United States continues to take a hard line, it could increase tensions in the region.

By and large, America's failed "regime change experiment" in Iran remains committed to promoting democracy in the Middle East and working with allies to combat threats like terrorism. Still, this does not mean that the United States has given up on the region. Instead, it is looking for better strategies to meet future challenges.
