Going back over past drops and found something juicy!

What was the purpose of the sword dance that POTUS and the Saudi Prince performed?

The term 'ardah' is thought to derive from the Arabic verb ard meaning 'to show' or 'to parade'. It was so named because its purpose was to publicly display the fighting strength of a tribe and boost morale before an armed engagement.[1] Although there are regional variations of the particular rendition of ardah, the purpose it serves is nearly identical throughout the Arabian Peninsula.[1]
