It's been said that "war is hell" and certainly for those suffering through the consequences, hurt, and destruction of war, this is definitely true. However, when wars are fought in which one nation has far superior weapons, far superior technology, far superior infrastructure, and far superior trained personnel, the whole war is hell scenario, is more properly seen as war being hell for the side and the people that aren't able to properly defend themselves, at the same time being hellish for those conducting such a war with their boots on the ground, but for those supporting those boots on the ground, war often isn't all that bad.
In point of fact, for every soldier on the field of action, who is actuality really risking his body, and his life, it is estimated that there are seven soldiers behind him, that are relatively free of any reasonable concern that their livesare in any sort of danger or even concerned about suffering privations. Never, has the support troops to American soldiers on the field, had it so good. Nowadays, everything that an American support soldier needs in regards to health, food, sanitation, internet access, and social activities, is readily available for our troops, signifying that while war is most definitely brutal, cold, and lethal for those being assaulted by such, it's like a completely different world for those ensconced in safety zones.
While it certainly makes sense that America wants to take good care of its soldiers, there is a downside of making soldiers so comfortable away from home, so safe from danger, that they don't really truly comprehend the savagery of real war. Most definitely, those soldiers with boots on the ground are very cognizant of the brutality of war, the unfairness of it all, and the suffering that is created for the civilians who are in the wrong place at the wrong time, even though the place they are in, is, in fact, their native land.
The thing is, the superiority of American firepower and logistics is so significant, that the kill ratios, that is to say the amount of enemy combatants as well as collateral damage killed by American soldiers as compared to those American soldiers killed by the enemy is estimated by the independent.co.uk as: "US-to-Isis "kill ratio" 15,000-to-one." In general, the kill ratios in any of America's undeclared modern wars are at such staggering ratios in favor to America, that it seems both inexplicable and insane why any nation or organization would even consider going to war against America.
For those on the receiving end of the massive indomitable power and lethal destructiveness of American might, war, for those peoples is most definitely a living hell. On the other hand, the American soldiers giving the fight are, with the exception of those truly in the line of fire and in real danger, relatively speaking, a bit of a burden, an inconvenience, but not much more. This means, the masterminds of all of American skirmishes and wars, have created a playbook which pretty much reads as follows: keep our casualties down to an absolute minimum, treat our own personnel very, very well, and wreak as much havoc and destruction as we desire on our enemies, till world's end.
