First of all.... That thing'll NEVER fly... No wings or rotors means no way to keep it up, and if a soldier is needed to throw it into the air everytime you need a picture, I'd much prefer an awacs or a UCAV overhead... Or even a HUMINT resource on ground.
However. ReDevilJR is right about the "no soldier deaths". 70 years ago wars were fought overseas and noone knew anything except that now the troops had takken el alamein (or whatever), and usually people didn't know THAT untill days or even WEEKS later. Today war is transmitted on open air. Live TV straight from the front line, sometimes straight from the soldiers night cams, or the missles nosecam. INSTANT information. And while people today may not be as easily riled as they were 70 years ago. That tough hide that comes from watching too much death on TV doesn't mean that people dont care if it's their neighbour, friend, son, daughter, sister, mother, father, cousin or even a casual aquaintance of your wifes hairdressers' cousins' boss's mechanics son.
People CARE about their own getting killed. And modern day combat is being transmitted straight to our TV set over breakfast. So the governments of today will have to find a way to avoid casualties. One is to avoid armed conflict, however, this isn't feasible. So the other choice is to avoid direct combat. But in situations where you need a ground pressence, soldiers are (still) required.
However, there's so many nice and automated fighting systems in existance. And the ONLY reason they're not used is because these systems do NOT differentiate between a friendly and an unfriendly target if it's not transmitting an IFF. So why dont we just insert drones to fight every single war, and let god sort them out ? Simple, it's not going to look good on the morning news either that one country has just commited genocide in another country. If it was that simple, then the problem might as well have been solved with a nuclear bomb or two.
In essense: Soldiers die because people want their morning news over breakfast, and no amount of gadgets will fix that in the next 50 years.
