I heard that it was originally going be the Chinese invading, but it stirred feathers so they changed it to be PC. And now it is obviously absurd. I can’t enjoy a movie with a ridiculous plot.

The entire concept, starting with the original, was absurd. The same is true of nearly every film these days. You don't go to the movies for realism, you turn on the Military Channel.
And, the fact is that although China is the second largest market for American films, there is a strict quota in place and this film will probaly not even be distributed theatrically there.
