In this case you didn't need the WayBackMachine. The Wikipedia article for "24 March 2009, at 20:19" is included in the ordinary Wikipedia history. That version says, "Clinton compared the events of Kosovo to the Holocaust...The New York Times reported, 'On April 19, the State Department said that up to 500,000 Kosovar Albanians were missing and feared dead.'"
Thanks for that. When important info is scrubbed from the current page it makes me suspicious as to when it might be scrubbed from the history as well. I like Wikipedia, but I like the Internet Archive for keeping it honest even more.
