From a comment on— Jewschool thread, I thought I’d harvest this thought I have whenever I’m talking to advocates of a one-state solution:
A one-state solution would still be a two-state solution: the Jewish Israelis have all the wealth and representation in every national governing body. The Palestinians would continue as second-class citizens facing entrenched discrimination. Both peoples, deeply married to the concept of self-determination, would have to do an about face on a hundred years or more of nationalism.
The entire legal codes and national symbols of the country would have to be rewritten and voted into effect, which I can only imagine as problematic as what is happening in Iraq now. Violence would continue as terrorists and settler extremists continue to espouse ethnic domination and revenge. Riots between Jews and Arabs would be commonplace over each ill-executed (or resisted) attempt at integration of two peoples into one government, military, police force, education system, et al.
With open borders to the Arab world, I can only assume that fear of terrorism from abroad would result in the Jewish sector retreating into private security enclaves. Parts of the elite of both groups would leave the country, meaning Jews who fear their safety and Palestinians seeking better opportunities than minimum wage labor.
The Jews would find themselves as top dogs in a country still killing along ethnic lines; Palestinians would find themselves still fighting tooth and nail for equality. The journey to “peace” would be another 60 years in the making and quite possibly a retreat back into nationalism and a renewed two-state solution.
For the sake of preserving lives instead of intellectual consistency, I don’t think a one-state solution brings us closer to peace. In fact, I think it puts us further from it.
