When the Italian invasion of Ethiopia led to only mild protests by the British and French governments, on 7 March 1936 Hitler used the Franco-Soviet Treaty of Mutual Assistance as a pretext to order the army to march 3,000 troops into the demilitarised zone in the Rhineland in violation of the Versailles Treaty.[63] As the territory was part of Germany, the British and French governments did not feel that attempting to enforce the treaty was worth the risk of war.[64] In the one-party election held on 29 March, the NSDAP received 98.9 percent support.[64] In 1936, Hitler signed an Anti-Comintern Pact with Japan and a non-aggression agreement with Mussolini, who was soon referring to a "Rome-Berlin Axis".[65]
