Check out the stone in one of the murals , if you take a look at the contour for iran,afganistan and pakistan but flipped horizontally like viewed in a mirror you can see that it strangely fits the pattern
Also notice the contour of the helmets, resembling usa and older persian designs(the green leafs almost intentionatly cover part of the design)
The flowers are national symbols of the countries: poppy(Afganistan) and saffron(Iran)
Now i know that Leo Taguma(the painter) said that he doesn’t understand how people can see conspiracy theories in his drawings , yet he places that stone tablet depicting soldiers on a fire background coming from Afganistan to Iran
