If not execution, life in prison.
We have to stop letting people just get away with this stuff. When Jane Fonda went to Hanoi and was not charged with treason, we made it virtually impossible to charge anyone with treason.
Now, I know there are good and valid reasons to make the bar for treason very high, back in the 18th Century, the English Crown used treason as a catch-all offense.
But what this guy did was more than just wrong.
It was treason.
The US should still execute that bitch for treason, then move ontop the present problem that plagues us all.
As for this dipshxt he should tortured and then executed.. sloooooooooooooooowly.
