Classical liberals have long held that free markets foster peaceful societies. Many argue that free trade between nations will foster economic interdependence, and peace should ensue as a result. Nevertheless, there are many dissenters. While exploring the relationship between free trade and peace is important, it is only one part of 'economic freedom.' More research needs to be conducted to see how countries with high levels of entrepreneurship, low levels of corruption, independent judiciaries, and sound regulatory environments might be fostering peace.
