For clarification, the crimes committed by Manning, Wikileaks, and Assange, are "espionage" related, including providing material support to terrorist organizations, and in Wikileaks position, potentially being named as such an organization.
It is NOT treason.
From Black's Law Dictionary, 7th Deluxe edition:
"Treason, n. The offense of attempting to overthrow the government of the state to which one owes allegiance, either by making war against the state or by materially supporting its enemies."
The proper crimes start with "espionage".
Again, same Black's:
"Espionage - The practice of using spies to collect information about what another government or company is doing or plans to do." Under 18 USCA section 793, et seq., the act of "espionage" against the United States was criminalized and sets forth the punishments for espionage, spying, and related crimes. See 18 USC section 793 here:
linkTerrorism, as defined by 18 U.S.C. section 2331:
"(1) the term "international terrorism" means activities that -

(2) the term "national of the United States" has the meaning
given such term in section 101(a)(22) of the Immigration and

And, 18 U.S.C. section 2339B "Providing material support or resources to designated foreign terrorist organizations"
http://codes.lp.findlaw.com/uscode/18/I/113B/2339BManning and Assange both could be found guilty of being a "spy" (one who secretly observes and collects secret information or intelligence about what another government or company is doing or plans to do; one who commits espionage), as well as the "providing materials support to terrorists or terrorist organizations". See 18 USC section 2339, et seq, for that here:
link Wikileaks, as an organization, could very easily be designated a "foreign terrorist organization" under 8 U.S.C. section 1189, see here:
link "the organization is in a foreign country...engages in terrorist activities or has the capacity to do so...and such actions are against the United States."
It is NOT "treason". The punishments, however, are the same.
