As a retired Marine I know well that there are enemies within our ranks. He will be dealt with in a Marine like Manner, I trust you.
Keep your friends close and your enemies even closer.
Whoever does not have the stomach for this fight, let him depart. Give him his money to speed his departure since we wish not to die in this man’s company. Whoever lives past today and comes home safely will rouse himself every year on this day, show his neighbor his scars, and tell him embellished stories of all their great feats of battle. These stories he will teach his son and from this day until the end of the world we shall be remembered. We few, we happy few, we band of brothers; for whoever has shed his blood with me shall be my brother. And those men afraid to go will think themselves lesser men as they hear of how we fought and died together.
Off topic: I've always loved that speech and I know it's Shakespeare, but which play is it?
The Marines ain't going to take care of this guy. He is an ex Marine, which means they have no more jurisdictiction over him. But I bet he will be dealt with.
I too am concerned about the loyalties of some of our naturalized citizens. If we went to war with their former governments how would they stand? Is this question ever asked of them, No, I am not painting all naturalized citizens as traitors. We have a lot of of homegrown traitors in this country to, the Walkers and Hansen come to mind.
