Right. The point of difference between most post-mils and a-mils is how he makes his enemies his footstool. The former tend to think it's by the church taking dominion over the institutions of the world thus preparing a way for him; the latter tend to think that he will come to do that himself.

I personally seem to have a foot in each camp. I see the Kingdom as a present, peacefully implemented process (think parable of the leaven) ultimately completed (once the leavening reaches fullness and the last sheep is safely in the fold). This to be followed by the indisputable appearance of the King in all his glory and might, when "every eye" will witness his lightning-like presence and face judgement.
