News + market sentiment, last night the U.S. was aggressive and wanted to take action against Iran. Now it seems they are already lifting the blockade of the Strait of Hormuz. Are the Americans backing down?

After the U.S. lifts the blockade, Iran will see sincerity and go to negotiations; it all depends on the outcome. Based on previous information, Iran has always insisted on its nuclear rights, but it is well known that the U.S. definitely wants to dismantle Iran's nuclear program.
It all depends on what the U.S. offers Iran as compensation to get Iran to voluntarily give up its nuclear ambitions. Otherwise, there’s a possibility of continued conflict, especially since the U.S. recently reinforced the carrier strike group, and Iran has also claimed it is ready with enough ammunition.
