Sure.
I have no idea what motivates the language changes. I can't speak to that. All I can say is that they are out of step with international norm-building and with the kinds of language being used by countries all over the world to talk about the same set of international norms.
As for training, there's one thing I want to say about training on these issues--which involves understanding what this language means and involves the social and cultural norms that create gender roles--and that is the significant difference between saying “gender equality” and “equality between women and men”. This kind of training is not something being called for only by civil society organizations; this training is being called for by the head of international policing in the UN peacekeeping mission in Darfur. He requested that the Pearson Peacekeeping Centre provide them with training on the prevention and response to sexual violence. This was so successful that they offered a second course and then a third. I don't know if they've offered subsequent courses.
Likewise, Major General Patrick Cammaert, who was the Deputy Force Commander for the UN mission in the Democratic Republic of Congo, spoke about the need for this kind of training and the need for troops to understand, including, as a matter of the language of gender equality, what this means to their mandate, their role, and how they perform their duties. To quote Major General Cammaert, “It's not rocket science”.
His example was this. When he came upon some troops who were patrolling a displaced persons camp in Eastern Congo, they were inside their armoured personnel vehicle. There had been attacks on women and girls on the borders of those camps, and he said they needed to know that they had to get out of their vehicle and walk around the border of the camps. That's what we're talking about, and that's the point at which he said, “It's not rocket science”.
