Do you think the isolationist were correct in arguing the Roosevelt's policies including lead lease, would increase the likelihood of war?

One could argue that the Lend lease act and other laws like this would increase America's likelihood of war because it resulted in America clearly favoring certain countries involved in the war. Many of the arms and weapons deals occured with countries who were part of the Allies. Even though the US was supposed to be "isolated" it clearly showed America's support of the Allies over the Axis Powers.
