The US sub not picking up the sailors after sinking the ship does seem like a straight up warcrime.
I am done giving the US any leeway with the way they have been acting. Department of War, lethality, and the rest of their garbage.
Oh, I am right there with you. Fuck the US.
But I just like randomly flinging around words like "illegal" in the sense of "things I don't like". If we do not require ourselves to make sure what we say is true, then soon we will be no better than them.
