that wikileaks creator some years ago hacked pentagon. only reason he still walks the earth is because of popularity he gained with wikileaks. and still is possibility that he will "disappear" since that soldier sent him 100 of thousands of secret documents. there is no problem for any government to kill people they don't like - it's not like they always do the papers and let news stations to know that this and that will be assassinated because of this and that. specially in cases where someone hacks pentagon - if they want him dead they wont make it official.
just watch wikirebels movie:
