The West Bank has no sovereign status, it's disputed territory, having been captured from the Jordanian government, not the "Palestinians". As for atrocities and persecutions against "Palestinians", Lebanon, Jordan and Kuwait would be at the top of the list of perpetrators.
The West Bank has a legal status. It is legally occupied by the State of Israel. It has not been annexed by Israel. Therefore it is Occupied under the Geneva Comventions and the UN Charter.
When Israel accepted the 1947 Partition Plan, which gave the West Bank to the Arabs, they made it clear that they would accept a Jewish state without these lands.
Also, after the 1948 war, Israel was more then willing to accept the armistice lines with Jordan as Israel's border. They made no argument that the West Bank, then occupied and annexed by Jordan, was "disputed territory":
From Wikipedia-
"In the
Knesset then Foreign Minister and future Prime Minister
Moshe Sharett called the armistice lines "provisional boundaries" and the old international borders which the armistice lines, except with Jordan, were based on, "natural boundaries".
[13]. Israel did not lay claim to territory beyond them and proposed them, with minor modifications except at Gaza, as the basis of permanent political frontiers at the
Lausanne Conference, 1949.
[14]"
"Israeli Foreign Minister
Moshe Sharett, always the diplomat, had hoped for a comprehensive peace settlement at Lausanne, but he was no match for Prime Minister
David Ben Gurion, who saw the armistice agreements which stopped the fighting with the Arab states as sufficient, and put a low priority on a permanent peace treaty (Pappe, 1992, Chapter 9: The Lausanne Conference)."
