Here is Victor Davis Hanson on the fruits of American unilateralism in 1973.
Thirty years ago, during the Yom Kippur War of October 1973, most of the Europeans of the NATO alliance refused over-flight rights to the United States. We had only hours in which to aid Israel from a multifaceted surprise attack and were desperately ferrying tons of supplies to save it from literal extinction. In contrast, many of these same allies allowed the Soviet Union — the supposed common enemy from which thousands of Americans were based in Europe to protect Europeans — to fly over NATO airspace to ensure the Syrians sufficient material to launch and sustain their surprise attack on the Golan.
American “unilateralism” in those days meant acting alone not to let Israel perish. Had we gone “multilateral” and listened to our NATO allies — Germany, France, Greece, and Turkey all prohibited American planes from flying supplies in their space in transit to Tel-Aviv — there would be no Israel today at all.
