US-Iran War Escalates with Impending Economic D-Day Sanctions Amid Growing Domestic and International Backlash

Five months into the US-led war against Iran, the conflict has reached a critical juncture as the United States prepares to launch a massive round of economic sanctions, termed an "economic D-Day" by President Donald Trump. Designed to collapse the Iranian government, these measures coincide with a continuous US naval blockade that has already intercepted dozens of vessels. In response, Iran's military leadership has issued aggressive counter-threats, including halting all oil exports from the Persian Gulf, even as the Iranian rial plunges to an all-time low of 2.03 million per USD. Meanwhile, a Reuters/Ipsos poll reveals that the war is highly unpopular in the United States, with only 35% of Americans approving of the conflict and a vast majority fearing long-term regional instability and rising fuel prices.

// Background

Tensions between the US and Iran escalated significantly after the US unilaterally withdrew from the 2015 nuclear deal in 2018, initiating a 'maximum pressure' campaign. In response, Iran established a sophisticated sanctions-evasion network utilizing shadow tankers, shell companies, and overland trade routes through neighboring countries. The current armed conflict was initiated by the US and Israel in late February 2026, marking a dramatic shift from proxy warfare to direct military engagement.
