Cute. But then why would the public prefer all those resources go to Europe instead of being used aginst Japan? Your way might get Lindberg elected POTUS someday yet.
Um, read up on Lindberg more, and see the kind of public statements he had made by 1940 regarding Hitler, the Nazis, Fascism et al, and...Jews.

He was in Henry Ford territory, and worse by far than Joseph Kennedy Sr. And even Kennedy was a political dead duck by 1940 with his statements about America having to "save herself" by going Fascist.
John Q. Public knew what the America Firsters were. That if you ripped open their suit jackets, often enough, you'd find underneath a brown shirt.
As has also been repeatedly explained on these boards, Lend Lease won't and didn't effect the war against Japan one whit while the navy and shipping the US needs to take the war to Japan won't arrive until 1943. (1)
Germany's choice is to either do nothing while US flagged shipping supplies her ally Britain and turns the island into Airbase One or to attack the US at a time and place of Germany's choosing and before the US' rearmament kicks into gear. (2)
You seriously need to read more. Seriously. The support for isolationism in '41 is not what you believe it was. (3)
As you first assignment, check out US public opinion polls at various points in 1941 concerning the prospect of going to war with Japan and/or in Europe. They've been posted here recently so they shouldn't be too hard for you to find. You'll be surprised. (4)
1) While air and ground forces for fighting in Europe (OTL) can be made available more quickly.
2) Same formula for the Japanese ignoring the Philippines while the US is building up its navy and air forces.
3) I've noticed over the years that as time goes by people born in later decades appreciate less the changing political climate in the USA before its entry into WWII because of events going on in Europe, especially after the French surrender. Also, for young people today, events like the Rape of Nanking seem to be either forgotten, or dismissed. Like if the USA did nothing for Rwanda, then they must not have really wanted to do anything for China 60 years ago either.
Isolationism was a BIG issue until June 1940. It took a huge hit then, and never fully recovered. Barbarossa also bucked up the Interventionists.
So by Pearl Harbor, pretty much anyone in the know politically could sense it was only a matter of time. But everyone was expecting some unilateral crazy action by Hitler, not Japanese Warlords who were pre-doomed to fail. Even with all their OTL successes, it was like a champion flyweight boxer getting in a flurry of punches on a super-heavyweight. But the super-heavyweight only had to land one punch...
4) Especially regarding Japan. The American People seemed to think it would be as easy as going after a Fascistic Mexico!
Your second assignment is to find out Lindberg's standing in terms of his political popularity in 1937-38 versus 1940-41. The luster of herodom tends to fade when you develop political opinions. Incessantly attacking America's greatest 20th century POTUS (and third overall, after Lincoln and Washington in that order) turns that luster to tarnish.
