for the simple reason that they were fulfilling their duties, notified the UN in advance (and told them why) and because Israel was already outside of its sovereign borders -in Palestine - at that time, which the UN noted and sanctioned! Israel sent a communique to the UN about annexing Palestinian land outside of Israel's legal borders and the UN rejected its claim outright. This is why there are NO UN resolutions against what the Regional Powers did then. So that's that. But YES, the *inalienable* Right of Return exists and persists, regardless of Israeli wishes that it didn't, regardless how inconvenient or troubling to Israel it may be. Again, it is simply the consequence of Israel's acts and persistent intransigence. But keep in mind the RoR applies ONLY to the generation of refugees who lived in Palestine & Israel at that time, not their lineal descendants.
