Umkhonto we Sizwe (MK)

The time comes in the life of any nation when there remain only two choices:
Submit or fight. That time has now come to South Africa. We shall not submit and we have no choice but to hit back by all means within our power in defence of our people, our future and our freedom... refusal to resort to force has been interpreted by the goverment as an invitation to use armed force against the people without any fear of reprisals.
