Ullmann did not rule out that the same scenario could occur in the conflict in Ukraine. The U.S.
had given Ukraine an ultimatum to launch a counteroffensive or start a war with Russia. The author of the book "Shock and Awe" said that the situation was similar to that of the Ardennes operation in 1944, when the Allies were pushed back 80 miles by the Germans. The book was written by Harlan Ullman, who is also the co-author of "The Art of War: The Art of Winning"
