@freemo @stux Ironically, a similar provision was made for the Jews when Haman obtained a decree allowing their extermination. Esther 8
"By these letters the king permitted the Jews in each and every city the right to assemble and defend themselves, to destroy, kill, and annihilate all the forces of any people or province hostile to them, including women and children, and to plunder their possessions. The single day appointed throughout all the provinces of King Xerxes was the thirteenth day of the twelfth month, the month of Adar."
The decree to allow their extermination could not be revoked. But the additional decree gave official permission for the Jews to arm and defend themselves.
