Maybe I am just paranoid (but am I paranoid enough?), but I suspect that, even though we didn't see them, to foster amity , Trump let the Russians bring their own film crew and all. Then, he parades Putin right in front of some F-35's loaded with TS gear, none of which (other than the engine intakes) appears to be covered. Western journalist are probably not even paying attention, as it is background noise to them, but the Russian medias - some of which must be spies in disguise - are probably going "Bazinga! Get me lots of high-def close up pics".
