I apologize if I misunderstood you, but there is no both sides here. The united nations recognizes the right to armed struggle against occupation.

UNGA Resolution 37/43 (1982) reaffirmed the “inalienable right” of the Palestinian people “and all peoples under foreign and colonial domination” to self-determination. It also reaffirmed the legitimacy of “the struggle of peoples for […] liberation from colonial and foreign domination and foreign occupation by all available means, including armed struggle.”

It even mentions the Palestinian struggle explicitly.
