Christian Zionists are mainly evangelical Protestants. They take a pre-millennial approach to end-time events:
• The rapture of the church • The rise of the Antichrist • The seven year tribulation • The Battle of Gog and Magog when Israel is attacked • The abomination of desolation when the Antichrist breaks his covenant with Israel • The Battle of Armageddon when Jesus saves Israel from annihilation • The judgment of the nations • The binding of Satan for 1,000 years • The Millennial Kingdom when Jesus will rules the world, and Jerusalem will be the capital • Source: https://www.gotquestions.org/end-times-timeline.html
Here is a partial quote from an article about Zionism: https://www.gotquestions.org/Zionism-Christian.html
The Zionist movement, begun in the late 1890s, found fulfillment in 1948 when Israel was officially recognized as a state and granted sovereignty as a nation by the United Nations. This is when, technically, the political Zionist movement ended and the ideology of Zionism began, and as such, has become a much-debated topic.
Christian Zionism is simply Gentile support of Jewish Zionism as based on the promises to Israel found in the Bible, passages such as Jeremiah 32 and Ezekiel 34. Christian Zionists are primarily evangelical and give support in any way possible to the Jewish state of Israel. The return of the Jews to the Promised Land is the fulfillment of prophecy and is seen, especially by dispensationalists, as a sign that the world has entered the end times.
After a mass return of the Jews to Israel the Antichrist will make a 7-year peace treaty with Israel and the temple will be rebuilt in Jerusalem. Half-way through, the Antichrist will break the treaty resulting in worldwide persecution. Part of the purpose of the Tribulation is to bring Israel back to the Lord as explained in this article: https://www.gotquestions.org/Jacobs-trouble.html
I realise this is only one Protestant pretribulation view, but it might help you to understand the timeline of events as they affect Israel with regard to the Tribulation that comes before the return of Christ to destroy the Antichrist and the enemies of Israel. It’s a contentious subject and hotly debated. One thing is clear, though, and it is that God has not finished with Israel.
