Poland was very much in existence before the partitions, wasn't it?
What does that matter?
There were centuries when it simply didn't exist nor was it autonomous which is the same argument you are trying give for the Palestinians not "existing".
Congress Poland"Following the partitions of Poland at the end of the 18th century, Poland ceased to exist as an independent nation for 123 years. The Congress Kingdom of Poland was theoretically granted considerable political autonomy by the liberal constitution. However, its rulers, the Russian emperors, generally disregarded any restrictions on their power. It was, therefore, little more than a puppet state in a personal union with the Russian Empire. Thus, from the start, Polish autonomy remained little more than fiction."en.wikipedia.org/wiki/Congress_Poland
There never was a real country Palestine whose liberation has to be fighted for and freed!
Nor was there any real country of Israel before 1948.
Zionism originated in Central and Eastern Europe not Palestine. Zionists had to ask the British to be allowed to immigrate to Palestine.
This is all in the 1917 Balfour Declaration which mentions Palestine by name but Israel isn't mentioned anywhere.
The Balfour Declaration also recognizes "existing non-Jewish communities in Palestine" and makes Jewish immigration conditional in that their entry into Palestine must not infringe on the civil and religious rights of the native population.
By the way, the Zionists in Palestine were first ruled under the British. The British then turned control over to the United Nations.
It was the United Nations that first proposed a two state solution.
Therefore, there never was a real country Israel whose liberation had to be fought for and freed.
The country Palestine will be shiny and new no matter how it comes into being...
So? No different than the State of Israel being self-recognized for a mere 75 years.
If you believe Jewish myths then why don't they resettle to the lands they claim they spent nearly a century in exile (i.e., ancient Babylon which is now modern day Iraq)?
Heck, they can go way back to the homeland of their prophet character Moses (i.e., Egypt) where as a people they claim to have lived for over 400 years.
Or they can go live in the land where this Moses person died (i.e., Jordan).
