Blockade as a Weapon

The United States’ long-running pressure campaign against Iran raises a harder question: when does coercion begin to disrupt the global order? After decades of sanctions, the central objective remains unmet—Iran has not abandoned its nuclear program. Yet Washington appears to be escalating, moving beyond economic pressure toward actions that constrain passage through the Strait of Hormuz.

The demand that Iran halt uranium enrichment remains contested. As a signatory to the Treaty on the Non-Proliferation of Nuclear Weapons, Iran retains the right to peaceful nuclear activity. Critics cite compliance and inspection concerns, but dismissing treaty entitlements outright risks eroding the credibility of the very frameworks meant to regulate nuclear conduct.

Washington justifies its posture through deterrence and regional security. Yet restrictions on Hormuz carry systemic consequences—disrupting energy flows, constraining oil exporters, and imposing costs on major importers such as China, turning a bilateral dispute into a broader geo-economic contest.

Equally significant is the human dimension. Merchant vessels and seafarers become entangled in strategic signaling, raising concerns about proportionality under maritime norms.

Framed as strategy, such measures still function as instruments of pressure on civilian economies and global trade—effectively turning blockade into a weapon that demands closer legal and academic scrutiny.
