At a previous hearing last year, Manning's lawyer, David E. Coombs, described the treatment he received like that of a "zoo animal." Manning also took the stand during that hearing and described contemplating suicide and making a noose while being held in Kuwait.

Manning's treatment was excessively harsh. But he was on suicide watch for a reason.
He was mistreated while in captivity, it was excessively harsh, and it was uncalled for. But the hyperbole about it ("worse than death row") was too often over the top.
One doesn't "joke" about suicide in jail.
No doubt I'm not expressing this well, but I hope you get my point.
Snowden isn't going to be "tortured" or "disappeared" any more than Pollard or Walker or any of the other infamous US intelligence officers who gave up secrets. After his trial, if he's convicted, he'll probably be out in ~ 30 years like them, too.
We'll have to agree to disagree about the rest. ;-)
