(1) Get the UNGA to recognize that Palestine is "a state", and not just "a disputed territory". (2) With that under their belt appeal to the UNSC for help against a foreign aggressor in EXACTLY the same way that South Korea did in 1950. (3) When the USA vetos any UNSC action then go *back* to the UNGA for a "uniting for peace" resolution. The end result will be that the Security Council will be cut-out and, therefore, the USA will be unable to prevent Israel being placed under UN-sanctioned embargoes.
