That's incredibly fascinating - I had never heard of Christian Zionism before (though I'm obviously familiar with evangelical Christians in the US and their ideas about a Jewish state). It appears the term Chirstian Zionism first appeared in the mid-20th century, though the idea is older than that:

The term began to be used in the mid-20th century, in place of Christian restorationism, as proponents of the ideology rallied behind Zionists in support of a Jewish national homeland.

Advocacy on the part of Christians for a Jewish restoration grew after the Protestant Reformation, and is rooted in 17th-century English Puritanism. Contemporary Israeli historian Anita Shapira suggests that England's Zionist Evangelical Protestants "passed this notion on to Jewish circles" around the 1840s, while Jewish nationalism in the early 19th century was largely met with hostility from British Jews.

I like the idea that Zion i wherever Jews live/are at home. As far as I'm concerned, fighting anti-semitism and fighting Israel's version of Zionism is two sides of the same battle.
