People being far too literal here about the "Love the Lord God". Your God is whatever you worship, and yes even the Atheist worships something. The commandment is two parts: (a) Jehovah (The Lord) should be your God and (b) your God should be the priority in your life. If you're Atheist or another faith then replace A by identifying "your God" and make it your priority. Live with purpose!
I'm calling BS. I stopped reading after you wrote about Nazi Soldiers and Soviet Soldiers because that was the point I was sure you are a fool. Specifically gems like, "Nazi soldiers as not only dishonorable, but downright evil" and "unless we are willing to defend the Soviet soldier, who dutifully executed the orders of Stalin, we cannot pardon the American soldier" show how little you understand about the realities of life under Fascist/Despotic rule.
I certainly don't want to be an apologist for the terrible atrocities crafted and committed by the men on the ground of a war, but your stance is naive. You seem to have imagined-up to yourself Evil armies, populated solely by Evil men who could not wait to murder, rape, and torture. Then you conclude, "You are a soldier fighting for evil men, therefore you are evil". This is inaccurate.
The sad truth is a majority of Nazi and Soviet soldiers were average people and not that different from you or I. Almost none of these soldiers had any choice in the matter to fight for these Tyrannical Leaders. Both armies were populated mainly through conscriptions and drafts. In fact (and through my Russian family members, I know this to be true), you were guaranteed to be executed (and your family) if you did not join the army and serve obediently.
And you do not seem to understand the importance of Moral leadership, military and governmental, to the morality of the troops. What happens when you're ordered, under pain-of-death, to execute an evil order? You can resist, for which you are either executed immediately or more likely "disappeared" without the opportunity to be a martyr to inspire your comrades. Do not forget, your family will also meet the same fate: e.g. Stalin's Order 270. This environment eliminates the effect and actions of good men by killing them, corrupting them, or cowing them to the point of compliance.
Admittedly, I could only stomach the first few sections of your writing. But that was enough to offend me with your lack of understanding of history and humanity. It's easy sit in your comfy world, with freedom and a democratic government and call those poor souls "Evil", "Dishonorable", etc. You have these gifts out of dumb luck. If you were born in some other time or land without those gifts, you would likely find yourself walking in their shoes doing the things they did. That is sad and terrifying, but likely true.
There are bad men that serve in the American Military. But most of them are very normal people and a significant portion of them serve with honor. Our military is volunteer, which means the members had a choice to be there. In addition, our governmental and military leaders are moral for the most part. That makes it radically different from these Boogey-Man Armies you're equating them with.
You are comparing Apples to Oranges and doing a rather terrible job at it.
