Americans don't celebrate the Alamo as a failure, they celebrate it as a catalyst for the Texas revolution afterwards. If that hadn't occurred Americans wouldn't even mention the Alamo in their history books.

Americans don't celebrate Custer's last stand. Indigenous people obviously do, and should, but white people don't consider him a hero.

Americans don't celebrate MacArthur getting chased out of the Philippines, they celebrate his declaration "I will return" and the Allied victory.

Americans only support the underdog when the underdog wins in the end.
