Free trade jeopardizes countries' security.  If a country goes to war with one of its trading partners, it needs to have the capacity to produce all of the necessary tools for war domestically, and not depend on other countries for supplies and parts. Additionally there is fear that disease-causing agents and bioterrorism can enter countries through the trade of poorly inspected food1. For reasons of national security it makes sense to retain the capacity to produce what is necessary to win a war and to protect the domestic population. This is one of the reasons why countries—such as the US1—like to protect their agricultural industry. Free trade is a threat to global security. For countries to stay safe, they need to retain some protectionism in their international trade policy.  1 George W.
