What is the protocol about wearing them, or other foreign medals, after retirement? Or does that qualify you as a Walt?
Whatever the protocol, I'd say that if they were awarded to you, go ahead and wear them. Remembrance parades are already peppered with blokes covered in those pseudo medals such as the National Service Medal and many more which are available to anyone who wishes to shell out thirty odd quid a go. Pinning your Saudi and Kuwaiti medals under your official group certainly wouldn't qualify you as a Walt in my book - but mind you they are 'orrible medals - why bother?!
