Ah, here we go:
"In reality, Trump was attending the opening of the Global Centre for Combating Extremist Ideology along with Saudi Arabia King Salman bin Abdulaziz al-Saud and Egyptian President Abdel Fattah al-Sisi when the photo was taken. The state-of-the art centre aims to monitor and combat global extremism in real time. During the opening, the leaders in attendance placed their hands on an illuminated globe as a gesture of their combined commitment to ending terrorism, and to officially activate the centre by launching a welcome video on the screens above."

I had assumed something along those lines, but that's still no excuse for setting up the photo op to look like someplace James Bond needs to escape from while it explodes behind him.
I mean...
How are you going to have that room NOT look like a Bond villain base? It literally is one.
Naw, those are just storm troopers.
