Landmines can maim and kill civilians and are banned in many countries under the 1997 Ottawa Treaty. Yet on Europe’s northeastern border, these controversial weapons are making a comeback. Following Russia’s full-scale invasion of Ukraine, Finland, Poland, and the Baltic states are rearming and bringing banned anti-personnel landmines (APLs) back into their arsenals. While military and political leaders say they contribute to strategic deterrence, mine victims and deminers say they pose a serious long-term danger. The war in Ukraine has reshaped Europe’s security thinking and triggered a radical shift in Finland. According to Colonel Riku Mikkonen of the Finnish armed forces, the military considers APLs a cost effective tool for national defence and a pragmatic instrument of deterrence. But to Zoran Ješić, who lost a leg to a mine in the Bosnian war, these weapons continue to kill, maim and render entire regions uninhabitable even decades after conflicts have ended.
