>>The thinking is that viruses are not a likely threat.<<<br><br>I sure hope you are right, Beachdoc. Before last week, the thinking was that 4 small groups of suicidal hijackers crashing 4 airliners into 3 important buildings simultaneously was not a likely threat.<br><br>I see the possible backlash of using a viral weapon and I hope the terrorists have similar values about that kind of thing. Right now, I am not completely comforted by that assumption. I don't know what their values are. I also don't understand what the values of the Jim Jones cult was but people who are eager to die for a cause may not be motivated by the same fears that you and I would be. I don't know if it is possible to predict psychotic behavior.<br><br>Here's hoping that the current worldwide anti-terrorist sentiment will result in effective policies that keep us from ever finding out.<br><br>
