All of the consequences need to be considered if they redistribute the land forcibly from whites. Western nations have a history of empowering rebels and proxy Governments to destabilize African countries during transitions of power. This can be seen with Libya Congo Rwanda Zimbabwe Liberia etc.and then right after you say that.. you proceed to do a whole bunch of for the whites
South Africa has some of the best natural resources and best economies in Africa. To keep them from becoming competitive i can see western nations starting some shyt. They have even more of an incentive to do so if they start killing white people. Sanctions coups and proxy wars can easily occur with the flick of a wrist.
