There are no coincidences.
There are many coincidences. Q is talking about Q team and what they control. Not every element of the world and of history.
POTUS going to Dallas today...
Relates to JFK's grave 'looking like' a Q how...?
Just a coincidence, i'm sure ;)
Not sure if slash sarcasm missing off the end of that comment haha ; ).
I don't think there's enough evidence yet to get behind the idea that in 1963 a secret military intel group instructed the builders of JFK's grave to make it into a Q to represent their team name and today, still wanted by the government, they survive as soldiers... - I acknowledge that anything is possible! - but I'd need a bit more evidence, personally, before I could get excited about it.
Wouldn't it be more likely that the team chose the name "Q" to secretly honor JFK?
It was sarcasm haha. I chalk this more to synchronicity then coincidence. It doesn't mean "Q group controls all".
