"why do these "peace activists" speak only of pressure on israel?" Because without pressure on Israel, there never will be peace. " where is the economic pressure on the palestinians so that they come to their senses..." Is can be seen in a place called Gaza where there has been actually a full economic blockade for very long now. It can be seen in the Pal WB villages isolated from economic mainland by so-called ' fence'. It can be seen at roadblocks and checkpoints and other places as well. Put on your glasses will ya? Try YouTube. Hope this answers your questions satisfactually.
