Second: Poland's army is of comparable size to German one, probably would lose even in 1v1 war. Any outside help to Germany would mean Poland's defeat. And all countries in the world could intervene, as declaring a war that is not a defensive/approved by UN one is illegal. Countries in NATO would be obliged to help Germans even.
Even if US for whatever reason decided to help the agressor (really, REALLY stupid move, for many different reasons), they would have no chance against combined millitary of most of Europe, especially in Europe, where the war would take place. Yankes wouldn't even have chance to enter the continent.
