People complain about the UN doing nothing, but it's also important to remember it was literally designed to not be able to do anything if one of the security council nations -- USA, UK, France, Russia, or China -- vetoes it. And USA always vetoes anything against the Israeli government.
Considering the UN's hands are tied, I'm very glad they're at least using their figurative microphone and international influence to call attention to how fucked up the treatment of Palestinians is.
I don't know for others, but growing up American, Israel and its friends in Washington had done a terrific job of conflating any criticism of Israel with anti-semitism. What finally got me to re-evaluate my stance on the Israeli government a few years back was when well-known, respectable organizations like the Human Rights Watch and Amnesty International started using the word "apartheid" to describe the situation of Palestinians.
Hearing sources like the UN Office for Human Rights, the UN Secretary General, Human Rights Watch, and Amnesty International calling out the Israeli government's actions in strong, unequivocal terms like "war crime" and "apartheid" is a start. I wish they could do more, and I sure as heck am angry with US foreign policy in this, but I'm just glad the UN has the balls to actually call this a war crime.
