The reason for this is simple. Islam is never having to say you're sorry.
In a very real way everything that happens is, by definition, the will of Allah. A muslim could never apologize for anything, because since Allah let it happen it was his will. The muslim will not of course put himself in the place of apologizing for Allah.
That when infidels do something and Allah lets it happen, it must therefore *also* be In'sha'Allah... this seems to be ignored.
Funny that.
