I dont know what point you are making, without lend lease the Americas are isolated Europe Africa Asia and eventually India Australasia are under the control of either the Nazis Communists or Japanese. Lend lease was a deal between allies for mutual benefit. The USA may have eventually been the biggest winner financially but how would you price a dark age of Europe including Britain being ruled by Adolf? As I understand history Greece was liberated by lend lease weapons.
I don't know why i'm not getting through.LL was vital to Britain ,without it the country would collapse(unless you think a country at war can reduce armaments)
Obviously the Americans weren't being kind they were defending their interests.I'm not talking about the morality or if it was a good or bad deal.
