That's not how the Jews view it. Without a Temple they see themselves as not having a place to offer sacrifices for atonement. Seen that way you can understand their desire to re-build it.
For the majority of observant Jews there is, at present, no need for a temple. It is a very tiny minority of observant Jews who want to try and re-build the temple. Because in the mainstream of Judaism it is believed that the temple won't be rebuilt until the messiah comes.
As Christians we believe Messiah has already come, His name is Jesus. And that the Temple and all its significance now applies to Him and His Church. He Himself said, "tear down this temple and in three days I will raise it up again" speaking of His body; and as the Church is His Mystical Body the Church is likewise the Temple of God.
Therefore in Christianity a physical temple in Jerusalem will always be irrelevant.
When Christ returns in glory as Judge and hands all things over to the Father and God makes all things new, we read that in the Age to Come there is no need of a temple because "the Lord God Almighty and the Lamb are its temple" (Revelation 21:22).
What this means is that the desire of a tiny fringe of observant Jews to be provocateurs is not what the majority of practicing Jews, not to mention secular Jews, actually want. And it will accomplish nothing but stir divisions and create new conflicts where conflict is already extreme--if the past month of violence hasn't made that obvious, not to mention the past several decades of violence in addition to that.
So let's not pretend that rebuilding the temple would be a good thing even as far as most observant Jews are concerned. Because it's not.
I'm genuinely curious how many people who think as you do have ever bothered to really have meaningful conversations with Jewish people, or look at Jewish sources, or see what Jewish people actually have to say.
I feel like what I observe instead is a fetishization of Jewish people.
