Vice President Joe Biden's speech/lecture to the Bosnian Parliament sounded a bit brusque. See: Join Europe or Die. But I'm sure the legislators were properly chastened and set straight. Bosnians, Serbs, and Croats always respond well to a visiting Gringo who knows exactly what's best for them and isn't afraid to tell them so.
Incidentally, the White House was taking no chances with Joe the Gaffer on this trip. The Washington Times reported yesterday that the White House took the unusual step of releasing Biden's prepared remarks in advance, just to preempt any press corps confusion in the event that Joe should go off on a tangent.
