Tuhia he haere tonu mō tēnei wāhanga - I te hui 35 o te G8
I te Hōngongoi 2009, i whakapuaki ngā kaiārahi o te ao i to rātau tautoko i te whakataunga a Obama-Medvedev ki te whakakore i ngā patu karihi katoa, ā, i karanga atu ki ngā whenua katoa kia "mahi anō i ētahi atu kaupae i roto i te whakakorenga karihi". E whakapono ana ngā kaiārahi o Global Zero kei te eke te whakaaetanga o te ao mō te whakakore i ngā patu karihi ki tētahi taumata whakahirahira, ina koa ko ngā whakapuakitanga a ngā kaiārahi tōrangapū i te wā o te hui motuhake o te Kaunihera Haumarutanga o te UN i runga i te whakawhānui me te whakakorenga i whakaritea e te Perehitini Obama (24 Mahuru 2009). I riro i a Perehitini Obama te Tohu Nobel mo te Hauora i te tau 2009 hei whakanui i ana mahi mo te whakakorenga karihi.
