How many times am I going to re-write this after thinking about what I’ve just written??
That’s a bit like asking why people smoke if they have known for the last thirty years that it gives you cancer. People smoke for any number of reasons and still start smoking today.
I think there are going to be any number of reasons why people sign up and go out there. Some might be doing it to try and make it a country that would allow people to live in peace and without oppression for once in fifty years. Some might be doing it for the money or because they like a scrap. Some might be doing it because they don’t want to let their mates down. I went (albeit for only a short time) because I had a job to do.
I support them because it’s a difficult job that leaves them, irrespective of their motives or the motives of the executive, at the sharp end. They risk their lives for _us_ and people will sometimes hate them for being there when they disagree with why they are there. I support them because they support me.
It’s difficult to explain really.
