F3WMB,
Why shouldn't the Afghanis stone adulterers? Saudi Arabia does* and that doesn't stop most western Governments doing business with the House of Saud?
Reserves the right to, but usually carries out about 100 public beheadings a year instead (including one last year for sorcery)..so that's all right then.
You make a valid point, you cannot drag these countries from the 5th century into the 21st without using an awful lot of nuclear weapons and starting again from scratch or fence them off and let them kill each other.

These states have few indigenous population willing to put their noses to the grindstone and work for a living.
