Peace campaigners have also engaged in many activities which do not fall within either the categories of conscientious objection/draft resistance or opposition to nuclear weapons. There have for example been relatively successful campaigns to ban landmines and to achieve a treaty regulating the sale of arms, to prevent sales to repressive regimes or aggressors in wars. Much of this activity involves education and publicity or meetings, petitions and lobbying. But there is also a wide range of direct action, for example resistance to the siting or extension of military bases or firing ranges. A transnational movement against the arms trade includes both publicizing the extent and nature of the trade and regular demonstrations and blockades at arms fairs. In Britain the Campaign Against the Arms Trade publishes details of protests in CAAT News, and Peace News reports on demonstrations. The success of the international Stop the Shipments campaign in halting South Korean tear gas supplies to Bahrain (engaged in repressing internal protest) was celebrated in Peace News No. 2566 (Feb. 2014), pp. 1 and 6.
One important development since the 1990s has been the launching of global campaigns (drawing on a wide range of existing campaigning groups and mainstream NGOs) that enlist support from sympathetic governments to craft a UN treaty. This approach was initiated by the International Campaign to Ban Landmines in the 1990s and taken up by those pressing for the Arms Trade Treaty achieved in 2013. It is being used by a new coalition with the aim of banning AWS (autonomous weapon systems): the Campaign to Stop Killer Robots. Critics of this approach query the usefulness of those treaties that can be achieved (given the military and economic priorities of many states) - a criticism directed especially at the Arms Trade Treaty. The most militarily powerful states (and those engaged in long term conflicts) also tend not to sign conventional arms control treaties. But there is also a case for maintaining a process of extending arms control under UN auspices; and the existence of a treaty can be used by civil society groups and protesters to exert political pressure, and to appeal to international law.
