What, according to bismarck, would be the difference in effect of the editor of the edited and original versions of ems dispatch?

The ems dispatch was edited without adding or changing words, it was only reduced by eliminating some words, which in the end, according to Bismarck, the difference in the effect was not the result of stronger words, but of the form, what made the telegram seem stronger and decisive, while the original version would only have been considered as an unfinished negotiation.
