"Unrestrained zeal to make the world better could make it worse. Promoting democracy must be undertak..." — Richard N. Haass

Trade accords had been a staple of the post-World War II world, providing a mechanism for economic growth, development, and association with friends and allies, and a means of reining in would-be adversaries who otherwise would have little incentive to act with restraint.

Wars of necessity are essentially unavoidable. They involve the most important national interests, a lack of promising alternatives to the use of force, and a certain and considerable price to be paid if the status quo is allowed to stand. Examples include World War II and the Korean War.
