Headline: "Marking International Day of Solidarity with the Palestinian People in Uruguay"
      "The embassy of the State of Palestine in Uruguay – in coordination with the union of worker organizations and the human rights department – marked International Day of Solidarity with the Palestinian People in the main hall of the Association of Professional Organizations and [with] the participation of Ambassador of the State of Palestine Walid Abd Al-Rahim… Ambassador Abd Al-Rahim reviewed the history of the Palestinian struggle since the ominous Balfour Promise (i.e., Declaration) and the unjust resolution to divide Palestine (i.e., referring to the UN Partition Plan for Palestine; see note below), erase the name Palestine, and recognize the state that was established while bloody massacres were being committed by the Zionist gangs in order to expel the members of our people and bring the Zionist immigrants from abroad.
The Palestinian ambassador focused on the will to struggle of the members of our people and on the use of all means of struggle (i.e., term used by Palestinians, which also refers to the use of violence and terror)‎ in order to restore our people’s legal rights, return the Palestinian cause to the UN, and to bring about the states of the world's recognition of the independent Palestinian state."

The Balfour Declaration of Nov. 2, 1917 was a letter from British Foreign Secretary Arthur Balfour to Baron Rothschild stating that “His Majesty's government views with favour the establishment in Palestine of a national home for the Jewish people.” In 1922, the League of Nations adopted this and made the British Mandate “responsible for putting into effect the declaration,” which led to the UN vote in 1947 and the establishment of the State of Israel.

UN Resolution 181 (the UN partition plan for Palestine) was passed by the UN General Assembly in 1947. It called for the partition of the British Mandate of Palestine into separate Jewish and Arab states, with Jerusalem as a separate entity under the rule of a special international body. The Arab state was meant to be comprised of the western Galilee, the West Bank, and the Gaza Strip, and the remaining territory of the Mandate west of the Jordan River would be the state of Israel - Jordan (known at the time as Transjordan) had already been established in what had been the part of the Mandate that was east of the Jordan River. The resolution was accepted by the Jewish Agency for Palestine, but Arab leaders and governments rejected it.

The terms "all means”, "all means of resistance," “all forms,” are ‎used by PA leaders to include using all types of violence, including deadly terror ‎against Israeli civilians such as stabbings and shootings, as well as throwing rocks and Molotov Cocktails.
