Espionage can result in a death penalty but it's currently the case that the UK (courts) would like a guarantee from the US (lol) that he won't be executed. Other than that I think it's over 100 years and they can add more charges when he arrives.
This thread is a garbage fire - a bunch of people who didn't look anything up (or if they did, they cite no sources, so there's no evidence they did) spouting a bunch of mutually contradictory shit, all of it upvoted. I will never understand why anyone engages with Lemmy this way.
Sentencing guidelines usually have specific rules for whether sentences would be run concurrently or consecutively. Charges are grouped if:
(a) Counts involve the same victim and the same act or transaction.
(b) Counts involve the same victim and two or more acts or transactions connected by a common criminal objective or constituting part of a common scheme or plan.
(c) One of the counts embodies conduct that is treated as a specific offense characteristic in, or Chapter 3 adjustment to, the guideline applicable to another count.
(d) Counts use the same guideline and are included for grouping under [subsection §3D1.2].
A group's value is then determined by the most serious count in that group. Then, separate groups are combined in a way that is not as simple as adding the groups together. This United States Sentencing Commission PDF document explains how that combining is done. And this YouTube video explains more about how the severity of each charge is calculated and what that means in terms of time in prison, through the lens of explaining what it would mean if Trump were to be found guilty of all the charges laid on him in relation to the retention of classified documents.
I'm not even going to begin to try to work out how that would be applied here, because I am woefully unqualified. But I doubt it would actually be anywhere near 175 years for Assange even if found guilty on all charges and given the harshest interpretation of the sentencing guidelines.
That's nice, but it's only a list of "currently presented" charges, with none of the "potentially other" charges.
Keep in mind that federal felony charges involving the death penalty, like treason (¹), have no statute of limitations. He could easily get extradited, found either not guilty, or that the crimes have prescribed, or pardoned... then charged with treason and executed.
