Ah but Dave. The actuality of WW1 isn't something that the government wish us to celebrate. They like to see it as an example of serving your country (which means supporting them rather than criticising them.)

Jingoism isn't just good for recruiting sergeants, it allows us to forget how inefficient, unreconstructed and plain inept our military actually are. It is designed to give us a fuzzy warm feeling that young men in uniform who act rather than question, led by people trained to take on armies trained in the same way can somehow make us feel safe in the wake of fear stemming from a source they cannot tackle with their silly drill, medals and shouting at other ranks.

Which is ironic considering WW1 is portrayed as starting as a result of civilian terrorism.
