Here is my take on this, which is obviously based on my own experiences. When I was a young soldier, I attended by first prayer breakfast. I did find it odd that our chaplain would lead us into prayer asking God to allow us victory in war. As a young man, I really found that confusing. Asking God to take sides just appeared a bit odd. What I eventually learned is that soldiers to not hate other soldiers. We are asked to go into combat and win. This can be by killing our enemies or by incapacitating them until they are combat ineffective. To this end, we die if we must, kill if we have to, and show mercy if we can.
I my 39 years or military and law enforcement career, many a man has faced the business end of my weapon, but I was fortunate enough to neither die nor kill. Granted, where were many times I would have been justified in killing, but I was fortunate enough to be in a position to show mercy. One thing is for sure, I do not recall ever hating anyone. I can't claim that it was because of my Christianity, as this is a recent event in my journey from whom to grave, but it a fact none-the-less.
I hate no one. I was not around for WW2, but I am pretty sure I would hot have hated them either. I would have killed as many of "them" as I could, but equally as sure that I would not have hated any of them. I honestly believe you can fight a man, yet not hate him.
I've never contemplated the Biblical interpretation of WW2, but I know that there were good guys and there were bad goes. In this case, I am comfortable in claiming that we were the good buys. War is a barbaric act again brothers, and the aftermath political failure.
What I find equally as sad is that we have been at war for over 19 years (October 7, 2001) and many people do not even realize this. On the night we did our shock and awe there were babies who have now enlisted to continue fighting the same conflict.
Personally, I cannot think of a more honorable soul than that living within a soldier; regardless of which side of the battle line he or her is standing on.
My experience in this is that when you are at war, in a battle, no one fights for their country. We are actually fighting for our buddy who is next to us.
Then, there does come a time when our anger at what we have seen takes over our emotions and we do in fact become angry at those who are trying to kill us.
But that is just me.
