Boy! You really are that ignorant in this case...
This is recorded history. It's not open for debate. Pick up a book and read it sometime. You know, a book that doesn't have "pop-up" pictures and the like. A real book.
Just because it doesn't fit "your" version of the facts doesn't make it false.
When the British split the Mandate of Palestine up in 1948, most of it became Jordan, while the coastal strip was split into the Jewish State and Arab State.
The Arabs didn't like the partition, so they attacked and were defeated by the Israelis, who expanded their country. In 1967 (The Six Day War of 67). The Israelis launched a strike against Jordan, Syria and Egypt, and conquered the Golan Heights, Gaza Strip, West Bank (all three are still occupied) and the Sinai Peninsula (which was later returned to Egypt).
The UN asked the Israelis to pull back their forces to the border before the Six Day War, but they refused given that this was territory that was conquered in war.
So under international law, Israel is mostly for the Jews, but parts of it, the Palestinian Territories (Gaza and the West Bank), are illegally occupied and belong to the Palestinians.
The problem with the "occupied territories" is that Israel has a right to defend herself and if that means forming a blockade around the West Bank and Gaza, then so be it. Remember, the Palestinians elected a KNOWN terrorist organization to represent them as their government. At that moment, they pi$$ed away any credibility that they had or would have earned along with any and all respect.
