Afghanistan needs more well-trained Afghan soldiers and better Afghan police, but the question is who will pay for them? The country cannot afford to pay the additional costs out of its own limited budget resources—any further money coming from this source will be at the expense of much less funding for urgent development priorities like educating children, improving basic health, building public infrastructure, etc. Will the international community commit to provide predictable funding for a number of years for Afghanistan’s security sector? This is a critical backbone of the state, whose development is essential to over time progressively replace international military forces which are far more costly. Creating security forces without the ability to pay for them will lead to obvious problems. And while expanding the Afghan security forces, it is critical to ensure that sound oversight and accountability mechanisms are in place.
