Sure you could, but why would you spend the time to? And someone who cares about Wikipedia would just edit/delete it.
The more views a Wiki-definition gets, the more likely it's going to be correct (I bet that article gets quite a bit).
In addition, the article is a Featured Article (http://en.wikipedia.org/wiki/Wikipedia:Featured_articles),
meaning it has been identified as one of the best articles by the community. If you really think you can edit some falseness into the article, I'd dare you to try- we can see how long it would last.
And for politically charged articles like this, do you think your really going to get the whole story from one writer's view point? I challenge you to find a more nuetral, complete, and accurate summary of his life on the internet.
