By june of 1940, hitler had already done which of the following? check all that apply.

he had invaded russia.
he had conquered norway.
he had conquered great britain.
he had invaded the netherlands
he had pushed allied forces out of france.
he had forced the united states to join the war.

He hadn't yet invaded Russia. (this would happen only a year later)

He had already invaded, and won, over Norway and the Netherlands

He had never conquered Great Britain, so this answer is false.

He had won the Allied Forces out of France- in fact, this happened in June of 1940.

The US has not yet joined the war- it would not be for another year.
