Bird flu is no more dangerous than regular flu. Either "could" mutate to a type that is extremely deadly in humans and extremely contagious. Likewise it could mutate into something that is extremely beneficial to humans or mutate into nothing.
The bird flu scare is a gigantic waste of time. It has killed less people than a single plane crash and your chances of getting in a plane crash or far more likely than getting bird flu.
Of course the pentagon didn't invent bird flu, but Rumsfeld is nevertheless profiting from a billion dollar order for tamiflu from the US government since he is - coincidentally, I'm sure - probably the largest single shareholder in Gilead, the manufacturer of Tamiflu. Nevermind that Tamiflu has no known effect on human bird flu.
The US administration lives off fear. Bush mentions 911 at every public moment. Bird flu is part of the same fear effort. Both terrorism and bird flu are real problems, but no where near the threat the government wants you to believe.
