1) Jesus never once hinted of an earthly kingdom.
Disagree. [see my entire post, above
TDW (in post above): "[…] up to the time Jesus spoke His Olivet Discourse (and INCLUDING it), He only ever spoke of the promised and prophesied EARTHLY Millennial Kingdom (which will commence upon His "RETURN" to the earth)."
People tend to read the phrase "the kingdom of the heavens" and [incorrectly] THINK "UP IN Heaven" (or similar).
It is speaking of "the promised and prophesied EARTHLY Millennial Kingdom (commencing upon His "RETURN" to the earth)… and this is just ONE example, from the above post.
