You sound like a mouthpiece for the mullahs and ayatollahs of Iran, Hamas, Hezbollah, ISIS and Al Qaeda. They do not want anyone to support Israel.
But Christians need to keep things in their proper contexts.
1. The secular nation-state of Israel is there to give all Jews worldwide a homeland. That is precisely because of the hatred and persecution of Jews by so-called *Christians*. The fact that the Jews in Israel generally do not accept Jesus as their Messiah has nothing to do with this. And God did not given anyone a mandate to persecute Jews just because He caused their dispersion for their own sins. But European *Christians* believed that they had a God-given mandate to kill and massacre Jews. Thus Hitler came up with his *Final Solution*.
2. Israel stands against Islamist terrorism and Muslim domination, and for that reason alone it should be supported by all right-thinking people. Or would you rather see an Islamist Caliphate take control of the Middle East, and eventually the world? They would enslave or kill Christians, Jews, and all so-called *infidels*. Just remember the brutality of ISIS.
3. The religious beliefs of Jews in Israel are varied, but at the same time there are Messianic Jews who have believed on the Lord Jesus Christ. There are also other Christian groups in Israel. All Christians worldwide need to stand with Christians within Israel, as well as engage in humanitarian efforts within Israel, regardless of the beliefs of those who need help.
4. Jerusalem and the land of Israel are going to be the focus of the Second Coming of Christ, and Christians are to pray for the peace of Jerusalem. In the meantime, any government which supports the defense of Israel against its very real enemies should have the support of Christians. Obama was a crypto-Muslim and wanted to see the destruction of Israel. Trump, on the other hand, gives Israel 100% of his support in words and actions. But you don't like that.
5. Paul -- speaking by the Holy Spirit -- warns Gentile Christians not to be high-minded in their attitude towards unbelieving Jews. But you are violating that commandment of God, and showing contempt and disdain for unbelieving Jews. And that is unacceptable.
ROMANS 11
13 For I speak to you Gentiles, inasmuch as I am the apostle of the Gentiles, I magnify mine office:
14 If by any means I may provoke to emulation them which are my flesh, and might save some of them.
15 For if the casting away of them be the reconciling of the world, what shall the receiving of them be, but life from the dead?
16 For if the firstfruit be holy, the lump is also holy: and if the root be holy, so are the branches.
17 And if some of the branches be broken off, and thou, being a wild olive tree, wert graffed in among them, and with them partakest of the root and fatness of the olive tree;
18 Boast not against the branches. But if thou boast, thou bearest not the root, but the root thee.
19 Thou wilt say then, The branches were broken off, that I might be graffed in.
20 Well; because of unbelief they were broken off, and thou standest by faith. Be not highminded, but fear:
21 For if God spared not the natural branches, take heed lest he also spare not thee.
22 Behold therefore the goodness and severity of God: on them which fell, severity; but toward thee, goodness, if thou continue in his goodness: otherwise thou also shalt be cut off.
23 And they also, if they abide not still in unbelief, shall be graffed in: for God is able to graff them in again.
