Nevertheless, Nasrullah actively used his political power to assist the German-Turkish efforts. When the Turko-German Niedermayer-Hentig expedition was welcomed to Kabul in 1915 (despite promises to the Viceroy of India that the expedition would be arrested), Nasrullah provided a friendly ear to the mission after Habibullah reaffirmed Afghanistan's neutrality. Nasrullah was involved in introducing the expedition to journalist Mahmud Tarzi, whose papers began taking an increasingly anti-British stance. He also continued to entreat the mission to remain in Kabul despite Habibullah's unwillingness to offer them a solid alliance. Finally in 1916 Nasrullah offered to remove Habibullah from power and take charge of the frontier tribes in a campaign against British India, but by then the mission realised such action would be fruitless and declined.
