The men and women of the armed forces risk their lives over these wars. The public funds them with taxation. The wars have cost as much as 7 years of a 50% tax cut for everyone earning under $500K.

They did publish the `Spy Files Russia` documents in 2017:
WikiLeaks publishes what they get (after verifying credibility). They cannot publish what is not leaked to them.
Also: they did publish things on Russia.
