These costs should be shared by all the countries who are effected by this. USA alone can not put up with the cost worldwide. Countries like India and Saudi Arabia should also pitch in with money. USA presence in Afghanistan has pushed all terrorists in Pakistan. Pakistan is getting hit by them everyday. Ignoring Pakistan with no money will hurt the cause. Money giving to Pakistan is drop in a bucket. When we see the cost of fighting against extremists in Iraq. Afghan border and hills of Pakistan along the Afghan border tougher challenge that Iraq.
