Because Hamas did not recognize Israel and earlier agreements a substantial part of the international community, especially Israel and the United States, did not accept the Hamas government. Sanctions to undermine the Palestinian Government were imposed. After the massive arrest of PLC members and ministers by Israel, nearly a third of the parlement was detained.
After Hamas democratically won the elections, Israel in conjunction with the United States, threatened to restrict the movement of money, people and goods into and out of Gaza Strip and West Bank, if Hamas would become part of the new government. Israel demanded Hamas to recognize Israel's right to exist, to forswear violence and to accept the validity of previous Palestinian-Israeli agreements.
