Are Palestinians Insane?

Dear Ziad
Insanity is defined as many things.  The Talmud says it is one who throws his money purse into the sea.  Einstein said it is someone who keeps doing the same thing and expecting a different result.  Psychology defines it as doing things that are against one's better interest.
So aren't Palestinians "insane"?  They do things against their own better interest, they keep doing the same thing and expect a different result, and they throw their money away. 
Wouldn't it be better to psychoanalyze the whole group and provide psychotherapy?
