What should engineers do in taking part in Weapons development?

Engineers   need  to  examine   one’s  conscience   to  take  part  in  any  form  of  weapon development.

- They  have  to  consider  the  circumstances  leading  to  the  specific  conflict  and  decide whether it is justified to take part in associated weapons development.

- If necessary, they should refuse to be a part of it and be prepared to face consequences.
