Emoticon, there are rabbonim who permit ascending the temple mount. When I was in high school, I had a Rabbi as a teacher who held that the fact we control Har Habayis, we should 100% be bringing karbanos.
I know some people who have had the pleasure of going on Har Habayis. The spoke about what an amazing, spiritual journey it was. They went to the mikvah before hand and prayed really well.
Perhaps this is the start of Moshiach. Showing Hashem we WANT it.
