Gee, I don’t know about the UN existing before Israel but it seems to me Israel existed a little more than 2000 years ago. The Palestinians and other Muslim countries have no intention of letting Israel exist. Looking at the map that the UN wants to divide Israel would be like the French deciding they did not get a fair deal when they sold us the Louisiana Purchase and the UN deciding they are right and demanding the US cede the land back to France. The land in Israel that is contested is also land the Arabs lost when they declared war on Israel and lost and now seem to think they should get that land back.
sorry buddy, but the ethno-religious myths hold no water. If you want to go that route, then you need to also recognize the Palis are simply converted Jews which kinda ruins your whole argument and leads you down a path you certainly do not want to go.
The state of Israel was first recognized in 1948. The borders were defined by UNR 181 in 1947.
