Madame Butterfly is the most performed opera in the United States.

America wants to show Japan that he knows he messed up.

He doesn't know if he'll ever be forgiven.

So he'll keep showing it until he gets a response from the butterfly he's wounded.

"Im sorry Japan.. Really am.."

I honestly am not an AmeriPan shipper but I think this headcanon is rather adorable. Not to mention I want to get everyone's ship in this book not just RusAme.
