Seems like if that request is denied then he’ll have confined himself to the embassy for nothing.

Except this whole subthread started over a remark that what he went through wasn't as bad as how the US treats people in its jails.

Which was still bad enough to deserve a written condemnation from the UN.

The US simply ignores all these reports by various international oversight organisations such as the UN, or the ICC (there are strictly per definition no war criminals among US citizens isn't that great).

So yeah, ending up there, especially after you pissed them off, is something to be avoided at all costs.

Doesn't mean that someone is deserving of any and all treatment that is strictly "not as bad" (because that's a pretty friggin low bar).

Not necessarily. If the UK refuses the request, they likely would have accepted the request from Sweden, and Sweden may have then turned him over to the US.

The OP is about how Sweden has dropped it’s request.

So? For most of his confinement, Sweden was prepared to extradite him, meaning the confinement wasn't for nothing even if the UK refuses the request.
