BEIRUT, Lebanon — In its campaign to throttle Iran into submission, the Trump administration has in the last several weeks applied smothering force — blocking the country’s last avenues for selling oil, classifying the elite Islamic Revolutionary Guards Corps as a terrorist organization and deploying ships and bombers to the Persian Gulf.

But if the goal of increased pressure was to force Iran to change its behavior or to send angry Iranians into the streets to ultimately sweep the nation’s clerical leadership from power, it has so far achieved neither.

Instead, it appears to have only stiffened Iran’s resolve, pushing it from wary patience to calibrated confrontation against an enemy it has long mistrusted. Its leaders, analysts say, are determined not to capitulate to what they view as economic and psychological warfare, or to negotiate under duress.
