The influence of those who hold futurist doctrine has been nothing but a monstrous disaster for US policy.
Iran will be part of the "Gog-Magog" invasion of Israel. Thus, I don't thing there'll be any large-scale war between Iran & the US at this time, as this would result in Iran's devastation.
The great problem is inordinate support for the 1948 nation of Israel, as if Biblical prophecy predicted the event, & anticipated that event before Jesus returns for resurrection & judgment. There is no such teaching from Jesus & the Apostles.
That support is costly particularly to US taxpayers & the Palestinian people, also to the nations that have been destroyed because they are deemed a thread to Israel.. European Jews are not all of Abrahamic descent, & if they were, their corruption negates that descent, as both John & Jesus taught them.
Mat. 3:7 But when he saw many of the Pharisees and Sadducees coming to where he was baptizing, he said to them: “You brood of vipers! Who warned you to flee from the coming wrath? 8 Produce fruit in keeping with repentance. 9 And do not think you can say to yourselves, ‘We have Abraham as our father.’ I tell you that out of these stones God can raise up children for Abraham. 10 The ax is already at the root of the trees, and every tree that does not produce good fruit will be cut down and thrown into the fire.
John 8:39 “Abraham is our father,” they answered.
“If you were Abraham’s children,” said Jesus, “then you would[fn] do what Abraham did. 40 As it is, you are looking for a way to kill me, a man who has told you the truth that I heard from God. Abraham did not do such things. 41 You are doing the works of your own father.”
“We are not illegitimate children,” they protested. “The only Father we have is God himself.”
42 Jesus said to them, “If God were your Father, you would love me, for I have come here from God. I have not come on my own; God sent me. 43 Why is my language not clear to you? Because you are unable to hear what I say. 44 You belong to your father, the devil, and you want to carry out your father’s desires. He was a murderer from the beginning, not holding to the truth, for there is no truth in him. When he lies, he speaks his native language, for he is a liar and the father of lies.
That is no reason for "Christians" to persecute Jews - or any non-believers. We have the Gospel for them. If they reject the Gospel, they face God's judgment. But as far as we are concerned, Jews, Muslims, Hindus, atheists, etc, are people made in the image of God and are commanded to repent & believe the Gospel. Politically they should be allowed to lived & worship in peace.
