I don't see it as 'normalising' the horrific injuries, more like acknowledging them and not hiding them away. I watched the Choir when Gareth Malone brought together a number of former service personnel, most of whom were suffering some kind of post trauma and others who had been badly physically injured as well. I found it very moving.
It goes without saying that we should be striving to stop sending our young people to fight, especially in wars that the majority of the population demonstrate against, like the invasion of Iraq. Watching what is happening in Syria is beyond awful but I'm relieved the UK parliament voted against our direct involvement.
The Invictus Games are run by charitable funding I believe. Ex service personnel are over represented in the prison, drug, alcohol and mental health population. That has always been the case. One of the major problems now is the cuts to those services, and the huge increase in homelessness as a result of that and the shortage of housing, lack of housing benefit to under 25's etc. We are not a poor country. We need to invest in all our people and I agree, those who serve deserve to be prioritised.
