The end Justifies the means.
Did the policies of Otto von Bismarck coincide with those suggested by Machiavelli?
Well, I did not read \"The Prince\".
But the question should not really be, whether Bismarck did anything it takes to stay in power, because (according to the constitution of this time) Bismarck was not really the ruler. The ruler was the Emperor (at this time Wilhelm I.), and he was able to appoint and dismiss the Chancellor (Bismarck) whenever he wanted.
But this is just as a remark. If you want to discuss the policy of Bismarck, one should probably divide it into two parts: before 1870/71 and afterwards.
Before 1871 most efforts were to unite the different German countries under the leadership of Prussia. In 1871, after the victory over France, Wilhelm I. was crowned German Emperor in Versailles, and thus the German Empire was established, and Bismarck was appointed Chancellor of the German Empire.
Now one could possibly talk about anything it takes to stay in power.

One of the main goals of Bismarcks foreign policy was to keep peace in Europe. The reason was, that Germany would hardly benefit from a war, but it could lose much and a war could cause disturbance in the domestic policy. And, another reason, Germany had quite difficult contracts with Russia and Austria. In case Prussia would wage war against Austria (or vice versa), Bismarck would have been quite in a mess....
