On October 14th Gordon Brown, the British prime minister, pre-empted the debate in Washington. He said counter-terrorism against al-Qaeda, without a counter-insurgency strategy to help Afghans take charge of their country, would not produce lasting security. Britain would send 500 more soldiers—on condition that the Afghan government deploys more Afghan troops to fight alongside them, and that other allies step up their contribution (probably at a meeting of NATO defense ministers in Bratislava on October 22nd).
