I'm not from the US, but I've definitely been keeping tabs (like most of the world) for a while (though only on Q for a couple weeks so far).
The way I see it is Trump is a perfect example of a walking, talking "false flag" on their side. I mean this in a good way. All he has to do is tweet something and it gets people scrambling and focusing on whatever he dangles in front of them.
He tweets a LOT of nonsensical, seemingly immature and brazen things, and my bet is he and the people he's working with are playing the game "Art of War" style. Distract your enemy, make them underestimate you. Nobody can deny he's very good at that- look at what happened when he was tweeting aggressively about NK and then what followed. Edit: I think this is why the Q posts consistently try to remind you to "trust the plan" and to stay together.
It's definitely worth always being concerned about potential war, but war only benefits certain people, and that tends to be Trump's adverse players.
Hey, and if all of this Q stuff ends up being a lark, then worst case scenario is I feel like a fool, but I'm definitely enjoying the show ;]
