How did Adolf Hitler break the treaty of Versailles?

In 1933, Germany completely stopped paying reparations, and began to rearm. In 1934, they began to build their air force -- the Luftwaffe. In 1935, conscription was reintroduced in Germany, and the armed forces increased to five times the size it was before. The re-militarisation of the Rhineland happened in 1936, which was a major breach of the treaty. The Allies didn't do anything about these breaches of the treaty because they were following a policy of appeasement, and giving in to his demands in the hope that he wouldn't start a war.
