CMV: Israel should have been established within the borders of Germany as an independent state following the Second World War.

The establishment of Israel is often cited as necessary based on the need to protect people of Jewish heritage from around the world. To the victors go the spoils. Why should an Israeli state be established in a historically relevant but highly dangerous location because of an historical claim that is thousands of years old? Why not annex a portion of Germany, relocate a population whose government actively worked to destroy the Jews, and work towards acceptance of Jewish visitors in their Holy Land? I am very aware that not all Germans were complicit in the actions of the Nazis. However, the annexation of a portion of Germany is arguably more morally justifiable than basically conquering Palestine because of a religion-based claim. If Jewish security is the issue, lopping off a portion of Germany to form Neo-Israel would have been the vastly superior option. CMV.

As with everything about the Palestinian situation, it isn't that simple.

There had been a steady flow of Jewish immigrants into Palestine since the end of the 1800s.  In 1936, the area as 28% Jewish with 384,000 Jews.  In 1946 that had grown to 543,000 (although growth in non-Jews kept the percentage to 30%).

The Europeans didn't want a Jewish state within Europe, and frankly didn't care a whole lot about the Palestinians.  Instead, you had a territory, mostly godforsaken desert,   which had been kicked around by a bunch of owners where the Jews wanted to move to, and where they'd be out of the Europeans hair.

The Allies discovered after WWI that imposing harsh penalties on Germans doesn't end well  - that wasn't a mistake they were likely to make again.

There wasn't a "Palestine to conquer" as you say, because it was already owned by the British.    

And since the original partition plan divided the land relatively fairly, it wouldn't have been a huge deal - except that then all of the Arab states declared war which the fledgling Jewish state won, and captured land in the process.
