Why isn't 5.7x28mm the NATO standard?

Although the 5.7x28mm performed well in NATO trials against competitors like H&K's 4.6x30mm, it was not standardized due to disagreements among member nations, particularly Germany. This political deadlock prevented a unified decision, and 9mm remained the standard.
