Military Commanders

Adolf Hitler was an outstanding leader. Rose through the ranks and became the chancellor of Germany. Massive world power. Almost conquered America.

Though we don't agree with what he did, he almost had world power.

Wut? Almost counquered America?
He was never even close to invading America.

Indeed he did. The Battle in which the British forces were stuck behind enemy lines almost resulted in the President surrendering and giving Germany power over Britain. If British forces were taken over, their force matched America, and we'd be speaking German if the war continued 3+ years.
