There are many views on interpretations of Revelation and those that think that Rev 11 is suggesting a prophecy of a rebuilt temple have very strong reasons to do so.
Now you have a strong opinion on why you interpret it the way you do, but others believe they have a stronger reason.
It appears at first reading that calling the two witnesses the two olive trees and the two lampstands, and knowing what that meant in Zech (that the temple would be rebuilt by Zerubbabel and his enemies would not be able to stop it) suggest that, that is the message in Rev 11. Those that believe that have
extremely strong evidence for that interpretation in the reference to Zech 4. It is so strong I don't know why anyone would ignore it. The key to understanding it is clearly handed to us with the statement
They are “the two olive trees” and the two lampstands, and “they stand before the Lord of the earth.”[a]
Rev 11:
11 I was given a reed like a measuring rod and was told, “Go and measure the temple of God and the altar, with its worshipers. 2 But exclude the outer court; do not measure it, because it has been given to the Gentiles. They will trample on the holy city for 42 months. 3 And I will appoint my two witnesses, and they will prophesy for 1,260 days, clothed in sackcloth.” 4 They are “the two olive trees” and the two lampstands, and “they stand before the Lord of the earth.”[a]
Now check out Zech 4
1 Then the angel who talked with me returned and woke me up, like someone awakened from sleep. 2 He asked me, “What do you see?”
I answered, “I see a solid gold lampstand with a bowl at the top and seven lamps on it, with seven channels to the lamps. 3 Also there are two olive trees by it, one on the right of the bowl and the other on its left.”
4 I asked the angel who talked with me, “What are these, my lord?”
5 He answered, “Do you not know what these are?”
“No, my lord,” I replied.
6 So he said to me, “This is the word of the Lord to Zerubbabel: ‘Not by might nor by power, but by my Spirit,’ says the Lord Almighty.
7 “What are you, mighty mountain? Before Zerubbabel you will become level ground. Then he will bring out the capstone to shouts of ‘God bless it! God bless it!’”
8 Then the word of the Lord came to me: 9 “The hands of Zerubbabel have laid the foundation of this temple; his hands will also complete it. Then you will know that the Lord Almighty has sent me to you.
10 “Who dares despise the day of small things, since the seven eyes of the Lord that range throughout the earth will rejoice when they see the chosen capstone[a] in the hand of Zerubbabel?”
11 Then I asked the angel, “What are these two olive trees on the right and the left of the lampstand?”
12 Again I asked him, “What are these two olive branches beside the two gold pipes that pour out golden oil?”
13 He replied, “Do you not know what these are?”
“No, my lord,” I said.
14 So he said, “These are the two who are anointed to[b] serve the Lord of all the earth.”
So setting aside the opinions of these men you mention and whether they were prone to violence I think that if you are honest you will see that if one were to use only the bible as their method of interpreting Revelation they would have strong reason to think that Rev 11 is a prophecy of a rebuilt temple.
I agree that it will not be approved by God for Israel to do it, God is not putting his stamp of approval on the Israeli efforts to reestablish their temple worship, it will simply be something that they do and God has foretold it before it happens.
Now before you start calling me a Jesuit or a Dispensationalist, or a Darby-ite or a johnny come lately, please skip all that and tell me another interpretation of Rev 11 if it is not referring to a rebuilding of the temple prophecy. I am sure you have a spiritualization. I hope it does not have to do with the pope as I find them rather outdated. What did E.G. White have to say about it?
