Iran's Performative Art

In the words of the great philosophers, "But why?"

This just continues to be strange.

Iran has moved a mock-up U.S. aircraft carrier to the strategic Strait of Hormuz, satellite images show, suggesting it will use the look-alike vessel for target practice in war games in a Gulf shipping channel...“We cannot speak to what Iran hopes to gain by building this mock-up, or what tactical value they would hope to gain by using such a mock-up in a training or offensive exercise scenario,” said Commander Rebecca Rebarich, the spokeswoman for the U.S. Navy’s Bahrain-based Fifth Fleet.

While the strangeness of this does not change and one wants to just mock it and move on, you also need to examine the Red Most Dangerous COA.

Iran is not a rich nation. It has a lot of challenges. What are they doing that makes this worth the investment? It can't just be for the performative art of it all, can it? 

What is the worst reasonably expected use of such a mock up? I hope we have some smart, imaginative, and skeptical eyes on this and what they are using it for.
