The UN is urging member nations to come up with the money and the troops to expand the Afghanistan peacekeeping force (ISAF). Afghan leaders and aid organizations have been calling for this, but UN member nations are reluctant to send troops into a nation with the most heavily armed civilian population in the world. The current 4,000 man ISAF force is restricted to the capital, which has, as a result, the lowest crime rate in the country. Even so, gunfire is often heard at night and rockets fell near where the Loya Jirga was meeting last week. Peacekeepers in other parts of the country would not only have to deal with criminals, but also warlords and tribesmen who simply don't like the idea of armed foreigners being in their vicinity.
