What would the practical implications of this actually be? My first thought is that NATO countries would stop selling arms or partnering militarily with Israel. Though I'm not sure if that is set in stone, the US has a habit of arming and working with groups, especially in the middle east, that either are designated as terrorist groups or act as one and are only missing the official designation.
