UA's shortest (and only) flight from TLV is TLV-EWR.
But actually there is no real workaround. Even in a parallel universe where NH allowed OW awards, a OW from EWR-TLV would cost 38/63/90k (being in the 4-7k miles zone). A longer itinerary would get better value (e.g. EWR-TLV-EWR-XXX - 11-14k miles which costs only 60/90/140k)
