After the franco prussian war why did germany form alliances and start to build up its military

Germany feared that France wanted to recapture Alsace and Lorraine.

Explanation:

Bismarck arranged a series of alliances with several other countries to reduce the threat of war against Germany and to protect themselves in the event that war did occur. They also wanted to isolate France, who the Germans were convinced would try to recapture the disputed territories of Alsace and Lorraine.

the big stick policy was to still look powerful, and be nice at the same time. the big stick policy was also to countries who were at war, find peace with eachother.

the dollar diplomacy was to expand american business and get it to latin america, for that would be good for the economy.

you my friend, your regards.
