The United States and Russia/USSR have been adversaries for a long time. Their heated rivarly stretches back to the waning days of WW2, when the enormous Red Army was occupying large swathes of eastern Europe, and the allies recognized the inherent threat.
The Cold War followed, when the two nations aimed an absurd number of nuclear warheads at each other. Then came the Space Race, when both nations vied for the prestige of making it to the Moon.
The US won that race, but the rivalry didn’t cool down.
