This is a very good and important article and makes points I also have made in my own writings. My own host father while an exchange student in northwestern West Germany in the 1980's had been one of those exiles forced to flee East Prussia to allow its annexation by Russia. There are 2 important points I would add to the article however.

1. After German reunification in 1990, the question of Germany's eastern border and claims for reclaiming Prussia and Silesia from Poland were in the minds of many in Europe. With the collapse of the Soviet Union, Germany as the more powerful country could easily have demanded Poland return some or all of these territories and sparked a war by doing so. Chancellor Kohl wisely did the opposite. He said that Germany accepts the judgement of history and finalized the eastern German border along the Oder River renouncing all German territorial claims in Poland despite these areas having been ethnically German for 1000 years or more. This insured peace in that part of Europe for Poles, Germans and Czechs.

2. Unlike the Germans who were expelled from Poland/East Prussia, the Palestinians were given a choice to have their own state alongside a Jewish Israel in 1948. They refused the offer of 94% of the territory in Israel and Jordan and attempted to massacre the Jews so they could have ALL the territory. They lost that war with Israel gaining its pre 1967 territory and Jordan and Egypt taking the West Bank regions of Judea and Samaria and Gaza respectively. They did NOT create a Palestinians state in those regions. Also, unlike the Germans of Prussia and Silesia, a significant part of the Palestinian population were actually recent Arab immigrants to the Levant who had come to the region from other Arab countries seeking employment in the areas reclaimed from desert by the Jews! Rather than seek to build a friendly state side by side with their neighbors, they sought full control by genocide. The Palestinians have not shown any change in policy in the last 75 years and all their respective "governments" have passed laws demanding that their state by Judenrein (Jew Free). Sadly, this accords with the Palestinian position during World War II when their leadership sided with Hitler and sought to extend the Holocaust to the Middle East.

Given these facts, it is fair to conclude that the Palestinians have demonstrated that they cannot have a state in peace alongside Israel and should be expelled from the region in the interests of peace for all in Israel, Lebanon, Jordan, Syria etc. The fact that even Arab states don't want the Palestinians says something about them and makes their future one of diaspora....at best.
