I think he is referring to the famous demand from Bin Laden: "America
must apologise for having a backward system of measure - or else we
shall blow up the Rockafeller Center!".

It became officially obsolete when various European governments imposed
their systems of measurement on the Arabs, as for example the French
imposing the metric system on the Tunisians in 1885.

The reason that 3-jaw chuck exists is to adapt to any system: US, si
or Sears.

Thus, the specification of the drills included adapting to any size.
The reason for the generic is becuase there were more than one flavor.

Well, that's because you're a woman and so never feel the need to
apologise.

Oh, here we go again. I've used both systems. You, obviously,
have not.


> Why do you?

_I_ don't, obviously!

But you just stated that you do feel you have apologize. Your
whole theme is based on your unwillingness to do that action.
