Because generally speaking it caused the second world war, and after the WWII the winning leaders didn't want another war for a harsh treaty, that's why there were "no sanctions" for Germany in 1945.
To answer your question more precisely, Hitler ended with the Treaty of Versailles as soon as he got in power. How? He started rearming secretly; he unificated Austria to Germany; and it all ended when the second world war started.
