Norway announced it will resume relations with the Palestinian Authority. This means Norway will restart aid shipments of supplies and money to the Hamas-led unity government. The various governments of the Western world originally cut off aid after Hamas' electoral victory in early 2006. Iran has been able to offer some monetary and military support to the Hamas government in the meantime. This relationship has led Hamas' Palestine to be in the very rare minority of Sunni governments who support Iran and Hezbollah.
Norway seems to be Nixon going to China. Several other EU countries are planning on resuming support to the Palestinian Authority and Arab states are putting pressure on America to recognize the new government. The United States blessing is the prize for Hamas. If it can get American aid than no one can doubt Hamas' legitimacy and it will be able to bank roll its expanding power base.
The real wild card in this situation is violence. Fatah and Hamas have always had an on-again, off-again low level civil war in the Gaza Strip. If violence is ended or severely curbed than more recognition and power will come to the Palestinian Authority. If Fatah or Hamas resumes the conflict though the government will collapse and aid shipments will stop. It is hard to say what will happen.
