The US did not have any standing agreements to aid Poland in the event of an invasion, France and Great Britain did.
There was no need for the US to pick a fight with Germany just for the sake of fighting.
Many of the British felt a strong racial tie to the Germans. Some also felt that joining the war because Germany invaded France was an incredibly foolish and misguided idea that seriously endangered Britain.
Britain was the enemy of the volunteers, so naturally they were not going to fight with their enemy, so they stayed out of it.
They were scared of Communism
Britain and France sees both Russia and Germany as potential threats ,after the Russian revolution Russia was hitting hard in world politics and economy so Britain and France hoped for a typical war between Russia and Germany (as Germany was becoming the world superpower ).Their was that If Russia And Germany could collide one would destroy another and there will be at least one enemy wipped out or weekend and would be easy to handle,this strategy was called as satisfying spree but unfortunately Russia and Germany came under an agreement not to attack each other ,that's why France and Britain refuses the Russian overtures for alliance though they gave (as announced) their full support to Russia when Russia managed to stop Germany's progress in Stalingrad .
They were in a preceding conflict with France, causing Great Britain to be in War Debt, and they did not want to fight a war while still in debt.
The countries involved in WW1 had taken losses in population unlike any other conflict in the history of the world, so they were reluctant to enter another confrontation until Germany directly invaded an ally of Britian, Poland in 1939.
Because they were afraid to fight them
in the treaty of Versailles Britain and France wanted Germany to pay for damages it caused in Europe, when in fact that Germany's ally Austria-Hungary and some eastern slavic nation started the war. and from that, the treaty made Germany one of the poorest European nation in the world, like the German Mark (German currency at that time) had no value in it that Germans would use it for kindling to warm their houses
Made it easier for Mussolini to invade Ethiopia. Made it easier for Hitler to invade Europe. Used as a pretext to refuse any help to the French republic in 1939-1941, while France was at war against Hitler. Prevented FDR to offer more than consolation to Great Britain after the fall of France, until late 1941.
George Washington refused to help France in its war against Britain primarily due to his commitment to neutrality. He believed that the United States should avoid entangling alliances and focus on its own national interests, particularly in consolidating the newly formed nation. Additionally, the U.S. was still recovering from the Revolutionary War and lacked the military resources to intervene effectively. Washington's stance was solidified in his Farewell Address, where he warned against foreign alliances that could lead to conflict.
No, the Patriots were happy to have help. LaFayette came from France. Baron von Steuben from Germany to help train the Patriots. However, you must also understand that Britain and other countries had been fighting in wars for years. All of the countries had financial burdens from prior wars on European soil.
