For the price of the Iraq War, we could've bought every US soldier who died in Iraq their own nuclear-powered submarine, so they could explore the ocean instead of being dead.
Sturgeon class submarines were sold until 1990 and are still in use today. They are around 300 feet long, are powered by a nuclear reactor, and can dive to 1300 feet. They cost $320 million each in 1990 dollars, or $530 million each in today's money. 4204 American soldiers have died in Iraq. Each of these soldiers could've been given a submarine instead for $2.23 trillion, which is $770 billion less than Joseph Stiglitz and Linda Bilmes' estimate of $3 trillion for the total cost of the Iraq War.
