Actually, John, I have posted extensively in this forum about the history of the region. I have even been chastized by Wolfgang for posting too many links while doing so. A search of my posting history would bring up many of the answers to your questions already posted by me.

Trying to place responsibility for the displaced Palestinians onto the countries surrounding Israel/Palestine instead of onto Israel itself is an obfuscation and a rationalization for unacceptable behavior on the part of Israel. The displaced Palestinians are Israel's responsibility and problem first and foremost. Any mistreatment of the displaced Palestinians by the countries to which they fled in terror from the Europeans who were slaughtering them and chasing them from their homes was/is despicable. But it would never have happened if they hadn't been chased from their homes in the first place.

The treatment that Jews fleeing from the Nazis experienced from some countries who wouldn't let them in during WWII was despicable, but it doesn't in any way free the Nazis from responsibility for what they did. You will tell me that what happened to the Palestinians during the Nakba is in no way comparable to what happened to Jews during WWII. This is true. But the comparison I've made here is appropriate because it addresses specific situations that are comparable in each event rather than the entire event. The European Jews were fleeing for their lives. The Palestinians were also fleeing for their lives. Had they not been, they would have stayed in their homes.

My interest in the plight of the Palestinians in Israel/Palestine, and my responsibility (my complicity) in this matter is direct and material since it is my tax dollars that are making Israel's mistreatment of them possible. I have a responsibility to speak up and not be silent on this issue as long as this mistreatment continues. I have not been inconsistant about speaking up when I have a responsibility to do so. I have spoken up about the despicable and sometimes criminal behavior of my own government in other countries whenever I have become aware of this misbehavior, and also about it when it happens here. I will not be silent and complicit about these things. And as long as several billions of US tax dollars go to Israel every year to make it possiblit for Israel to do what it's doing, I have a right and a responsibility to speak up about it. And so do you if you live in the US.

I still don't have time to hunt up my old links and find new ones for you, but if you really think it's important to read what my answers to your questions are, you can take the time to search my posting history and find many of the answers to those questions for yourself. Believe me, I have already spent many, many hours doing the research, and posting it here.
