Ignoring the somewhat predictable and repetitive nature of this thread, there is one very obvious difference between military and civilian training which is overlooked. All military pilots have been tested and have successfully demonstrated an acceptable level of aptitude during pilot selection tests. This simply means they have displayed an ability to scan, absorb, process and react to various information sources within an acceptable time frame and to an acceptable standard. This doesn't make you a pilot, but it does allow you to concentrate on the flying task without struggling to maintain situational awareness when in the cockpit. I don't know the fail rate currently, but it used to be about 50% of the applicants.
As a civilian pilot, aptitude remains an unknown quantity until you are in the cockpit on Exercise 1. If we extrapolate the rough statistic, about half of those students will do perfectly fine, but the other half will be working very hard to stay the right way up (figuratively and literally). Those that work to develop better aptitude will inevitably end up taking more time, and burning more money to get to the required standard, but for a small number they will always be on or outside the competency boundary. Some instructors will recognize this, others may not. If the student keeps paying, who cares how long it takes, right?
So what?
Well it means that military trained pilots generally have one less means of killing themselves and their passengers, in that they have demonstrated flying aptitude. It doesn't mean there are no stupid, arrogant, wilful or just plain dangerous military pilots out there, of course there are. It just means that while they are being stupid, arrogant, wilful or just plain dangerous they are probably fully in control of the aircraft with the requisite situational awareness. The same rule applies of course to the civilian trained pilots who also have the requisite level of flying aptitude, they have just never been formally tested for it.
Most of us can be aviation professionals, whichever route we choose, but the military mitigates the risk against those who might not have the capacity for professionalism at an early stage.
