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.

By that definition the by far most cited example on the British side, Dunkirk, doesn’t count because Britain won in the end.

No one celebrates someone who was defeated if the defeat wasn’t memorable. Usually that was because it was an inspiration to rally a cause that was later successful.

Plenty of white people celebrate Custer. Search for “Custer statue” or drive around out west and see how many paintings of Custer’s last stand you can spot hanging in bars.
