I believe it would have been better to have the man in sight than to make him dissappear.Sometimes it is better to leave the mole and wait for him to act before you do likewise rather than let him dissappear and loose all the information you could have gained.

as to the last line Paul,society is dynamic and just like Europe have learned to shape their society to meet their current needs.it would be so with Africa.

but look at the other side,if we kill ourselves and leave the whole vast continent empty of people but full of all the unimaginable resources,wouldn't it be best for the exploiters.
