Bismark’s strategy and goals for Germany were defensive after 1871, with Germany to become a peaceful status quo power. On accession, Kaiser Wilhelm though favored a policy of aggressive colonial acquisitions and building Germany a large and potent army and navy that would assure her primacy in Europe against France and Britain, one way or another. Wilhelm soon clashed with and dropped Bismark, adopting a program that set Germany toward WW I.
There were other groups more bent on expansion.
Wilhelm II. was not in favor, but, as you know all too well, history is written by the victors. Always has been, always will be. The historical narrative has to sound good.
