Read my comment again, I think that if you are a billionaire the US govt wont kidnap you like what they do in China and Russia.
I find your comment amusing unless you can give some sources where the US has kidnapped billionaires and kept them hidden for months.
I suggest you to educate yourself about the matter. He did disappear for years, not months, unfortunately.
And there is not need to become so defensive - if you look at history with intellectual curiosity you may find at certain point that similarities between US, Russian or Chinese government are quite extreme when it comes to fighting with forces opposing the government.
We are not talking about history here, we are talking about the present.
Still interested in reading your source for your claim that Assange disappeared.
Are those humans human enough for you?
