What kind of Christianity supports Zionism? I'm writing an essay about Christian Zionism, and I'm a bit unclear on the end-times beliefs of pre-millennialism and post-millennialism. I understand the basic timelines of both, but where does Jewish emigration to Israel fit in? At what point (and in which belief system) are Jews either supposed to convert to Christianity or be ruled by a tyrant?
Ellis Skolfield, a historicist (which is closer to Preterist than to Pre-Mil Dispensationalism) builds his entire framework for understanding Daniel and Revelation upon a timeline that has two of Daniel's prophesies pointing to the re-establishment of Israel in 1948 and the recapture of Jerusalem in 1967, respectively. 

Skolfield's interpretation of the "two witnesses" of Revelation is that one witness is the Christian church and the second witness is the faithful among Israel.

Thus to Skolfield, himself a Christian of Jewish ancestry, the modern nation of Israel is a direct fulfillment of prophecy and true inheritor of the promises that God made to ancient Israel.

Skolfield believes that the millenium and the tribulation occur at the same time. He argues that chillioi is an indefinite plural, so the prophecies about the Millenial kingdom should apply to a period of time that is millenia (plural), not millenium (singular). Thus as soon as Jesus ascended into Heaven, his millenial kingdom began. Likewise, as soon as the Apostle's prophesied the first persecution, the Tribulation began, and continues until today. That also means that the unbinding of Satan has already occurred.

Given that Israel was reborn, Skolfield believes that all prophesies about the end times have been fulfilled, except Christ's return, which can therefore be at any time. He said that many scriptures refer to the "Last Trumpet". He believes that they all refer to the same event, so that the final end of the tribulation and Christ's return and the rapture and the Seventh Trumpet of Revelation all describe the same event. There will not be two big battles, one at the beginning of the millenium and one at the end. There will only be one. The misinterpretation that he claims to correct is that Revelation presents a repetitive, telescoping timeline, which keeps backing up and going over the same time period repeatedly, giving different details. The structure of Revelation has confused people into thinking that there are two battles and a longer period of time than his interpretation requires for the time of the end.
