First this verse about unbelievers not Jews or Christians "strike them above the necks, smite their finger tips"8:12 This verse is about Badr war,At badr unbelievers fought muslim Do you expect god says:Kill them by injection or electric while the war is running it means kill them at war.As you know at Badr war muslim was not strong and unbelievers attacked muslim it's not about All unbelievers. "when allah promised to grant you one of the two parties (at badr), and you wished for the one that was not strong. Allah wanted to establish the truth by his words"8:7 God wanted to show muslim those unbelievers are lieing and if you are not strong they will attack you.
"it was not you who killed them, but allah slew them"8:17 God says you were not strong so I killed them not you. "if you desist,it will be better for you. If you resume we will return,and even if your forces are numerous,they shall not help you at all.
And allah is with the believers"8:19 God says to them after War:If you desist I will not fight you but If you resume we will return. There is like this in 47:4 And why don't you read your books? I don't know why do you know our religion better than your religion?
"Anyone arrogant enough to reject the verdict of the judge or of the priest who represents the LORD your God must be put to death. Such evil must be purged from Israel"Deuteronomy17-12 "Suppose you hear in one of the towns the LORD your God is giving you that some worthless rabble among you have led their fellow citizens astray by encouraging them to worship foreign gods. In such cases, you must examine the facts carefully.
If you find it is true and can prove that such a detestable act has occurred among you, you must attack that town and completely destroy all its inhabitants, as well as all the livestock"Deuteronomy 13-13,..,19 "Make ready to slaughter his sons for the guilt of their fathers,Lest they rise and posses the earth, and fill the breadth of the world with tyrants"Isaiah 14:21 "Kill anyone who refuses to listen to a priest"Deuteronomy 17-13 "You must kill those who worship another god"Exodus 22-20 "If anyone does not abide in me,he shall be cast outside as the branch and whither and they shall gather them up and cast them into the fire,and they shall burn"John 15-16 "Now kill all the boys. And kill every woman who has slept with a man, but save for yourselves every girl who has never slept with a man"Samuel 31-17 "Those enemies of mine who do not accept me as their lord, bring them before me and kill them"Luke 19:27.
Like the man said, That verse is about Badr war. "Surely those who believe, and those who are Jews, and the Christians, and the Sabians -- whoever believes in God and the Last Day and does good, they shall have their reward from their Lord. And there will be no fear for them, nor shall they grieve" (2:62, 5:69, and many other verses).
"...and nearest among them in love to the believers will you find those who say, 'We are Christians,' because amongst these are men devoted to learning and men who have renounced the world, and they are not arrogant" (5:82). "O you who believe! Be helpers of God -- as Jesus the son of Mary said to the Disciples, 'Who will be my helpers in (the work of) God?' Said the disciples, 'We are God's helpers!' Then a portion of the Children of Israel believed, and a portion disbelieved.
But We gave power to those who believed, against their enemies, and they became the ones that prevailed" (61:14).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
