The Nations in it
Explanation:
First of all, the triple alliance was an alliance made up of Austria Hungary, Germany, and Italy, but this was a defensive pact. So when Austria Hungary caused world war 1, Italy didn't join because Austria Hungary was acting like the aggressor, and later on Italy joined the allies against Germany and it's allies, so that's one of the weaknesses. This then left Germany and Austria-Hungary together, but the thing though was that Austria-Hungary was a super multiethnic empire and had too many revolts and uprisings, so this only left Germany, which was the only empire who performed well in the war, and that's another weakness.
The GDR stated it was constructed as an "antifascist protection mechanism" in order to keep out external threats and keep the east Berliners safe in their "Socialist Paradise" but in reality it was to keep people in since many were trying to emigrate out of the communist zone and the GDR would fall because of emigration.
