Final answer:
Hitler formed alliances with the Soviet Union and Japan during World War II.
Step-by-step explanation:
One of the new alliances that Hitler formed was the Nazi-Soviet Pact, also known as the Molotov-Ribbentrop Pact, signed in August 1939 with the Soviet Union. This pact was a mutual non-aggression pact that allowed Germany to neutralize the eastern threat from the USSR. Another alliance was the Tripartite Pact, signed in September 1941 between Germany, Italy, and Japan, which stipulated that the three powers would declare war on a neutral country that declared war on one of the others. The pact aimed to dissuade the United States from joining the war on the side of Britain, but it ultimately led to Germany declaring war on the US after the Japanese attack on Pearl Harbor.
