It can mean fighting for the people who happen to live here.
As far as I’m concerned all of “THOSE PEOPLE” can just die under the hobnailed boots of their conquerors.
I came back to the States to stay in 1972, I remember well how I was greeted at SFO; they can all die in the “COLD AND THE DARK” as far as I’m concerned!
I am willing to die for my fellow MARINE/SOLDIER/SAILOR/AIRMAN,
the rest can eat sh!t and die.
