No, he was talking about how it reigns already. He is lord and ascended on high, "though the eye of sinful man / his glory may not see." He was enthroned in the resurrection and allowed to sit at the Right Hand. Most references to the kingdom of God are about how it is at work right now.
No ordinary NT passage about the 2nd coming speaks of a millenium. Just one in symbolic materials that should not be used to found doctrine. That (Rev 20) is referring to the current age which ends with a short rebellion, the overthrow, and then there is the NHNE where God and Christ are the Light and the Temple. It will be physical, but physical will itself be too redeemed for us to imagine now.
You could be right that the millenium is a much shorter time than a thousand years but then it might be much longer as well.
It it men will not learn war, and the devil is bound and shut up in a pit.
So you will have a hard time to deny these facts.
Also,
Israel of the thousand years consists of Christians of no flesh distinctions.
