Where are the suggestions? Well, I have some...
1) give right or return to people whose former villages are now abandoned..I think there are quite a few.
2)   Have extensive vocational education for Palestinians. Have those who wish to become experts in mobile rescue operations...this can be done even from the camps...if there is an earthquake or natural disaster mobilize them to help with medical and construction help.
3) Find some employment that the world can offer them in cramped quarters..one thing that comes to me is optomotry..or making eyeglasses, dentures etc.
4) US and former colonies of British Empire offer massive immigration for millions of carefully screened people to get them out of camps.
5) Somehow turn around thinking so they can live somewhere else and still have Palestine as a homeland..like Mother Ireland etc.
6)   Repair of housing that has been bombed etc.
7) Trips out of the camps..excursions to other areas for peaceful vacations, work projects, help with harvests here and there..to help counteract the overcrowding etc....especially for children and young adults.
8)   More worldwide interaction..again much for children and young adults..they keep asking "why does the world hate us." (See Children International Site for messages from the children).
9)   Ways for them to continue their traditional arts (needlework for the women) and crafts.
10) Medical facilities in place so they do not have to cross checkpoints.
11) Ways for them to grow food in their occupied lands..
12) More respect in general for their history and needs..with simultaneous zero tolerance for terrorism.
13) Better control of what they are teaching kids in schools paid for by U.N. etc...stick to non-propoganda.
14) Ways to get the garbage and sanitation issues resolved.

That is all for now. mg
