They can't touch Mugabe's land. In any case, the new Zanu-PF farmers yield is not as bountiful as that of the white Zimbabweans. So, with a little prompting from Mugabe, they set upon the white-owned farms. Most likely, the veterans will run down the farms. The water systems will break down, the food storage will go to waste, they will slaughter and roast the farm animals in camp-fires over the next few months, then the farms will become barren.
Fate is a cruel mistress.
Another severe drought might visit Zimbabwe in the years to come. If Mugabe is still president then, he could very easily find himself begging for food for the poor people in the country, most of them former veterans on confiscated farms. Who knows, some of the very farmers who are being run off the land in Zimbabwe now could be the ones selling grain to feed the same hungry fellows who chased them off the land. However, if black people are to steal the land back, at least they need to do it with some style. Following the law and court rulings on the land issue, is one way of doing that.
