Those historians are correct, the difference is just racism. It is accepted that separate wars that started earlier merged into the greater WW2, why would the one with over 25 million casualties by some counts not? China (for a certain value of China meaning the KMT) even joined the Allies officially.
The real hot take is calling the Spanish Civil War a part of it. Mild spicy is the invasion of Ethiopia by Italy.
