I just got a visitor from a country that doesn't exist

So the other day I got a visitor from "Palestine." What country is this, I thought. So I started doing some research. Oddly enough, Wikipedia (and I am not suggesting Wikipedia is always right, because I would be laughing too hard to type that) apparently does not consider "Palestine" to be a country, describing it as "a geographic region in Western Asia between the Mediterranean Sea and the Jordan River. It is sometimes considered to include adjoining territories."

Oddly enough, Palestine could have been a country right after World War II:

The United Nations Partition Plan for Palestine was a proposal developed by the United Nations, which recommended a partition with Economic Union of Mandatory Palestine to follow the termination of the British Mandate. On 29 November 1947, the U.N. General Assembly adopted a resolution recommending the adoption and implementation of the Plan as Resolution 181(II).[2]
The resolution recommended the creation of independent Arab and Jewish States and the Special International Regime for the City of Jerusalem. The Partition Plan, a four-part document attached to the resolution, provided for the termination of the Mandate, the progressive withdrawal of British armed forces and the delineation of boundaries between the two States and Jerusalem. Part I of the Plan stipulated that the Mandate would be terminated as soon as possible and the United Kingdom would withdraw no later than 1 August 1948. The new states would come into existence two months after the withdrawal, but no later than 1 October 1948. The Plan sought to address the conflicting objectives and claims of two competing movements: Arab nationalism in Palestine and Jewish nationalism, known as Zionism.[3][4] The Plan also called for Economic Union between the proposed states, and for the protection of religious and minority rights.
The Plan was accepted by the Jewish public, except for its fringes, and by the Jewish Agency despite its perceived limitations.[5][6] With a few exceptions, the Arab leaders and governments rejected the plan of partition in the resolution[7] and indicated an unwillingness to accept any form of territorial division.

So anyway, there you have it. Not a country, but could have been a country, except Arabs all wanted the Jews dead and wouldn't accept a Jewish state. Why Google classifies them as a country is beyond me, but, hey, welcome to Eff You Nation. Which also is not actually a country.
