Why would Hitler sign a non aggression pact with Joseph Stalin even though he was extremely against communism?

He wanted to avoid a large enemy in order to further pursue his movement.

Explanation:

If Hitler can make peace with one of the largest armies in all the world and not have it interfere with his armies, then why wouldn't he? They didnt agree to be friends. Hitler later betrayed Stalin anyways, so he had mostly likely planned it for when his armies took more land and had more production going.

here are some major conflicts i found. maybe pick one and do more research on it. (cause i ain't writing 6 paragraphs)

in 1877, the nez perce war took place.

1881 - president james garfield was assassinated.

1882 - the chinese exclusion act was passed.

1883 - a decision in the civil rights cases legalized racial segregation in the united states.

1887 - the dawes act was passed.

1893 - the panic of 1893 took place. (what a creative name)

and there are probably other topics you can find if you just search up "united states timeline," or "conflicts in the 19th century for america."

then once you find a topic you like find out how it affected the people of america and what not. (sorry if this feels a bit short changed, history was and never will be one of my strong topics)
