Step by step...they are still maneuvering this situation toward some conclusion.
If you figure Trump will likely be around til 2024....it's fairly good odds that some type of treaty will be worked out...that simply says the War is over, and there's a new evolution taking place. Yeah....a 12-line piece that simply agrees there is no real conflict.
It won't happen in 2019. 2020 is questionable.
But it'll open up the door for the US to pull out a certain number of troops (24,000 US troops in South Korea today). My humble guess is that treaty will open up with 3,000 US troops leaving within sixty days, and another 10,000 a year down the line.
The end-result will be a small contingent....maybe in the 3,000 range by the end of 2024.
Trade will be established between the US and North Korea as part of this whole deal.
Some folks will be sitting there in shock....that Trump accomplished all of this, without any intellectual state department folks handling the process.
