World War I war tactics lead to the development of stalemates on both eastern and western fronts.  Although countries such as Germany were able to push forward and gain land through the use of infantry tanking, this allowed them to push through enemy lines and drove the allies back. The use of infantry tanking lead to the loss of many lives and Germans soon became tired and their exhaustion gave the allies time to regroup and Britain was able to push Germany back to their original fronts using their tanks.  This lead to a stalemate because although Germans were able to break through lines they could not hold their position leading to a counter that pushed them back to their original lines.  Stalemates on the Russian front developed because the Russians spread their armies thin on the frontier but were heavily fortified at bases along the way, while Germany could take the frontier they could not take the fortified points leaving them at a draw.  I think that with different war tactics were used there would have been a decisive winner of the war and the war could have ended much sooner than it did.
