I think a better way to frame this is “Is it possible to use the rule of law across national boundaries?” Clearly the answer is currently a qualified “yes”: Laws, treaties, etc do exist and are commonly used. The areas that are addressed are clearly not uniform, nor can we rely on all nations to participate, and the enforcement of laws across national boundaries are extremely tricky and currently limited. However, that should not stop us as a planet from trying to improve global cooperation through the law, rather we should look at it as “more work to do”.
