There can be no end to independent investigations and reports by NGOs but the Saudis and their partners will continue getting away with what they're doing. After all the popular narrative is that the Saudis and their partners are fighting ''terror'' in Yemen and want to restore a rightful leader to power. The West has other pressing matters to focus on; even if was willing to risk ties with Saudi over Yemen. The question really is what will it take for Saudi to come to a point where is enough is enough? They haven't got there yet; to admit failure now would be a huge embarrassment and would be a major victory for Iran.
