Van den Breemen has stated that Sheehan's comments are "total nonsense." You can find that in various sources, including wikipedia and here at the
WaPo.
I'm not sure how to respond to that. I would ask, though: do you think because he is a European general, as opposed to an American general, that he has less of a propensity for prejudice and narrow-mindedness? Have you considered whether this might have something to do with PR? The rapidity and fervour of the response, as well as the bare mention of any possible origin for the comments, makes me somewhat distrustful.
I just find it hard to imagine someone would stand in front of congress unprompted, lay the blame for Sebrenica on homosexuals, and then lie and state the basis for his argument originated with a Dutch general's comments. He's so forthcoming and unashamed of his highly unpopular comments, it just seems unlikely that he would worry about the PR he would receive, seek a scapegoat, and lie about an exchange with a Dutch general.
The American general has nothing to lose, and he seems pretty unabashed by his comments. Whereas the Dutch might want to avoid scandal, and so might the Dutch general, especially when tolerance is so highly prized by Europeans.
Since there's no proof either way, and the Dutch general did deny he made any such comment, he deserves the benefit of the doubt. But that's not going to lessen my wariness about what might have really been said behind closed doors.
