That's not true about the security council.

In fact the UN security council makes it clear in UNSCR 242 (1967) that the parties to the conflict need to work out territorial integrity, and ensure that Israel has safe and recognized boundaries "free from threats or acts of force".

The ICJ hasn't ruled on the legality of the occupation (and probably won't, unless they want to make fools of themselves), so your wrong there also.

The security and administrative arrangements between Israel and the PA in the West Bank is laid out in the Oslo Accords. The agreements were signed by elected representatives on both sides.
