Franconicus, I think it makes out troops realise what the army is.
They shouldn´t just join the army to get a job and sit around in Germany all day long, driking beer and enjoying their free time, it´s an army!
As peacekeepers they sit around as well, but at least there is some danger and they need to be aware of threats, I´d see that as a compromise between sitting around at home and real combat, plus it makes a few places on this world more secure.
Hollywood always says if you just change a little bit on this world, you already make a difference. I think it applies in this case. Though if you want to make peace and leave, our soldiers need to chase the criminals in the countries they are guarding.
And I don´t think you can compare that to the US in Iraq, I didn´t know we hire private companies for millions of Euros to secure those places.
