Could Germany's decision against the 1918 offensive have kept the war going long enough for the planned Wilhelmshaven attack?
Short answerPossibly, but a defensive strategy would hand operational initiative to the Allies and leave Germany in a poor position.
NotesIf Germany had skipped the 1918 offensive and held a defensive line, the war might have lasted long enough for the planned Royal Navy attack on Wilhelmshaven. That choice would also surrender the pace of operations to the Allies. It could extend the war without solving Germany's worsening strategic position.
