Are You Ready to Actually Retire?
Knowing when to retire is harder than knowing how much to save. The timing depends on what your retirement actually looks like: how long your money needs to last, what you'll spend, and where your income comes from.

Executive Summary
On February 28, 2026, the United States and Israel launched coordinated strikes against Iranian nuclear and military facilities, triggering the most consequential armed conflict in the Persian Gulf since 1991. Within 72 hours, the Islamic Revolutionary Guard Corps Navy (IRGCN) responded by activating the single most cost-effective weapon system in modern naval warfare: the sea mine. By March 10, CENTCOM had destroyed 16 Iranian minelaying vessels (CENTCOM, 2026, via Kurdistan24), but not before Iran reportedly deployed "a few dozen" mines into the narrowest and most economically critical maritime chokepoint on Earth (CNN, 2026).
The consequences have been immediate and systemic. Brent crude surged 65% in under two weeks, from $73/bbl to a peak of $119.50/bbl on March 9 (Reuters, 2026), exceeding every pre-conflict scenario projection. War risk insurance premiums for U.S.-flagged VLCCs transiting the Strait exploded from $250,000 to $10–14 million per voyage, a 40- to 56-fold increase in twelve days (Lloyd's List, 2026). Five major P&I clubs cancelled Persian Gulf war coverage outright (Reuters, 2026). Tanker traffic collapsed by approximately 90% (Forbes, 2026). The International Energy Agency responded with the largest coordinated strategic petroleum reserve release in its history, 400 million barrels, more than double the response to Russia's invasion of Ukraine (IEA via Axios, 2026).
This report presents a quantitative, scenario-driven risk assessment of Iran's mine warfare architecture in the Strait of Hormuz, grounded in the following analytical pillars:
5,000–6,000 mines; the largest and most diverse mine inventory held by any non-great-power state, spanning five generations of technology from Soviet-pattern contact mines to Chinese EM-52 rocket-propelled rising mines capable of engaging targets at 183 meters depth (DIA, 2019; CRS, 2025).
The Washburn ENWGS encounter-probability model,the standard U.S. Navy mine warfare planning framework, developed at the Naval Postgraduate School, applied across four deployment scenarios (50, 200, 500, and 1,000 mines), yielding per-transit encounter probabilities ranging from 3.6% to 52.1% (Washburn & Kress, 2009).
A generational MCM capacity gap, the Avenger-class minesweepers were decommissioned in September 2025 (U.S. Navy, 2025) and physically removed from the Middle East in January 2026 (Zona Militar, 2026). Their replacement, three LCS vessels carrying the MCM Mission Package, achieved IOC only in 2023 and has never been tested in combat (USNI News, 2025; Naval News, 2025). At historical clearance rates (~1.18 mines/day per task force), even a 200-mine deployment could require 25–50 days to achieve safe transit (CIMSEC, 2017).
The insurance-as-blockade mechanism, analysis demonstrates that the combination of physical mine threat, residual uncertainty after partial clearance, and cascading insurance market responses creates a self-reinforcing disruption loop in which even limited mining achieves strategic effects comparable to a declared blockade of the Strait (Stimson Center, 2026).
The central finding of this assessment is that Iran's mine warfare doctrine, rooted in three decades of post–Praying Mantis asymmetric evolution, has achieved operational validation in March 2026. A weapon system costing tens of millions of dollars has disrupted an energy corridor carrying 20.9 million barrels per day (EIA, 2026), imposed war risk premiums measured in billions, and forced the largest emergency oil release in history, all while fewer than a dozen mines may have actually been laid (Anadolu Agency, 2026). The question for U.S. and NATO decision-makers is no longer whether Iran can weaponize the Strait, but whether the Western alliance possesses the industrial, operational, and political capacity to keep it open under sustained asymmetric pressure.
