““One of the problems for the United Nations Expeditionary Force was that its members had no uniform apart from those of their own countries—yet they had to be distinguishable from the fighting men of Britain, France, Israel, or Egypt. Somebody at the United Nations came up with the idea that they should wear berets in the organization’s distinctive blue. There was no time to have them made, so the Expeditionary Force borrowed thousands of American plastic helmet liners, which were spray-painted blue.25 The blue berets or blue helmets of the United Nations would become an international symbol of peacekeeping for the rest of the century and beyond.””
