Answer:
The Treaty of Versailles was too harsh on the German people.
Explanation:
The treaty caused war guilt, colonial losses, and reparations. The economy of the German population suffered greatly, along with their territory and military. It is stated that Germany lost about 10% of it's population. Germany had no say into what price they had to pay to have this treaty, which made many Germans believe that the treaty was too harsh. This treaty was what caused much of the hostility between Germany and the other countries which would lead into the second World War.

NATO was designed to improve on the alliances of the past and to modernize the alliance system in light of the threat of nuclear power. The idea of collective security meant that war could trigger alliances linked on social, political and economic and ideological frameworks as well as a deterrent in terms of nuclear power.
