If I may add as well, I would say, yes, we've seen some impact already from the ATT when we look at the arms transfer decisions that governments are making around the world. Previously, there was no global regulation on the conventional weapons trade. We had a patchwork system of regulations where some individual countries had export controls that were quite strong, others had weak controls, and some had none at all.
One of the positive things that we've seen already with the 92 states parties that we currently have and 40 or so additional signatory countries is governments moving to put controls in place for both the export and import and also the transit of weapons through their territories, which is an important step towards reducing the diversion that a previous questioner was talking about. Diversion is clearly an enormous problem particularly in the field of small arms and light weapons, but not only for that, in terms of the illicit trade.
When we have analyzed specific countries, for example, relating to what Thomas was just saying with regard to arms exports to Saudi Arabia, we have seen some countries have stopped their arms exports to Saudi Arabia and associated coalition partners because of the humanitarian atrocities taking place in Yemen. Others have placed additional restrictions on their authorization mechanisms to reduce the number of weapons that are going to Saudi Arabia because of the conflict and the situation in Yemen. Yes, we are starting to see some changes in government behaviour both in terms of decision that they're making, and also around the world, importantly, in the establishment of systems where there were previously none.
