I think the op-ed was written in the NYT offices trying to bait Trump.
.or.
The other high probability is that Trump wrote it for the purpose of creating another shiny object for the NYT to chase because the Russia, Russia, Russia fraud is about to be exposed, Stormy is no longer of interest and he needs the cover of another false scandal.
Valuable piece of opinion from an old Freeper:
Anything that does not include the name of the source is total BS when dealing with the NYT.
When will we get to see what was in the side deals with Iran? They obviously had no interest in the main agreement as they did not sign it.
