I can understand why Israelis might be suspicious of the UN. The relationship between UN and Israel seems kind of fraught in a way that isn't true of pretty much any other country. The not allowing israel to fully vote until 2010 (edit: 2014), the (arguably) unequal focus only Israel's human rights record relative to other countries, and the whole UNRWA being totally different with different rules than any other refugee group, all make israel a bit unique in its relationship to the UN. I could easily understand how someone from Israel might feel that the UN treats them differently from other countries and is perhaps biased against them.
