  This year's commemorations of the start of World War One are a stark reminder of the sacrifices politicians make with other people's lives â€“ except nowadays they'll do so wearing a Help for Heroes t-shirt (almost entirely covering their brass necks). When it comes to the hypocritical lauding of the armed forces while simultaneously shafting them, no one does it better than this government.
