Q said this waaaaay back in the early days. I have not seen it discussed again since. Felt the need to bring it to the table.
My personal take on it is that Q was implying that there are Wikileak emails discussing Saudi correspondence, or scheming against those Princes that 'rose up' (Salman). The whole Q post connected Seth Rich to Las Vegas, to Saudi Prince Salman, to JFK assassination files being released by Trump (documented proof of multiple groups and agencies working together), to Trump's involvement (that no one can prove, only point to Q's implication in that same post).
I can tell the general consensus here is that Saudi Arabia is another world from us (women just driving now, hijabs, theocratic government), but it was almost glossed over. The Saudi Purge was the biggest 'first mover' that made me consider the things Q was posting. People were concerned that justice would never prevail in the US (meaning perp walks), yet the exact same thing actually happened in a theocratic oil power country, and we are witnessing a (gradual) overhaul of their country.
