You're insane. "Attacked?" A couple scouts wandered across the border. SK fired warning shots and they left. You call that an "attack?"
How many Americans have been killed by police shootings and ICE raids? Those are attacks! When fascists mobs beat trans people to death and the cops look the other way, that is an attack! We are currently under attack, right now. Not an attack 70 years ago, not thousands of miles away, not an "attack" that's a random soldier with a bad map, but intentional, organized acts of violence, with the intent of establishing a new, oppressive order in the United States itself.
It is beyond unreasonable and just full on delusional to think of anything else but complete and total focus on destroying the one, singlural existential threat that actually exists! They're at the fucking gates, my dude! They trying to kill us all! And there's a damn good chance they actually will!
What the fuck is going on in your mind to worry about this non-issue half a world away? A border skirmish? It couldn't even be called that! Warning shots, fired by South Korea? Are you out of your mind? Fucking hell! Look at what our own government is doing to our own people! I can't even go to work without thinking what would happen if a bunch of jackbooted masked thugs showed up and started shoving everyone into a van, to be taken to a secret torture dungeon in El Salvador!
Drop everything else. North Korea could be rolling tanks across the border as we speak, and it would still be less urgent then dealing with the fascists here at home! They want us in the fucking ground! What part of that do you not understand? They are an imminent threat to the entire world! North Korea doesn't give half a shit about us, except to the extent that we fuck with them! How can you have such completely ridiculous, mixed up priorities??
