The U.S. approach of "economic fury" combined punches is aimed at striking Iran's financial lifelines.

However, Iran's relatively healthy internal circulation economy and de-dollarization trade have caused multiple rounds of sanctions to show diminishing marginal returns.

Additionally, the coordination mechanisms between China, Russia, and other parties in finance and energy sectors have also undermined the deterrent effect of U.S. secondary sanctions.

Considering the fundamental differences between the U.S. and Iran on core issues such as nuclear programs and the Strait of Hormuz, relying solely on sanctions may be difficult to fundamentally shift the rigid stalemate in U.S.-Iran relations.
