The International Law on ethnic cleansing and the Torah law is similar in this case. Displacing civilian population groups solely because of ethnicity is wrong, even if they are allowed to live elsewhere. This is assuming not displacing them brings maximum protection of fundamental rights for all. Whereas if it did not, the displacement would not necessarily be wrong. It's not black and white in this direction or that but depends on the circumstances of each case. Ethnicity based cleansing (for its own sake) is not in the category of acceptable cleansing in this case. To put it in more colloquially familiar terms, the Palestinians Arabs are not a pure example of a modern Amalekite nation. There are too many roses in this thornbush to honestly make such a comparison.
An ideology of criminality within a given ethnicity, removes the shield against ethnic cleansing against said subgroup. For example, a drug cartel, can't seek to find extra protection under the law for reasons of bias against their race or ethnicity despite their crimes. Their criminal ideology and behavior makes them criminals under the law, it is all the other citizenry, not the criminals, who are entitled to protection from the police even if it would eventually lead to loss of many rights of the criminals were they be brought to justice. These matters are rudimentary concepts of criminal justice, yet they have seemed an elusive matter to grasp for some at the United Nations as well as at many World news media outlets.
Those who reject civilization among the Palestinian Arabs are a non ethnic segment, rather they are an ideological segment, and those are the ones to whom it is legal to relocate. Whereas the ancient Amalekites were completely the same in their ethnicity and ideology. They themselves made that distinction with their universal support of violence. If Palestinian Arabic radicalism reached 100 percent on both sides of the Greenline, God forbid, that would be after the Amalekite model, but that does not exist as an accurate monolithic standard in this case.
In Talmudic terms, let us consider, the great Hillel's golden rule of "'not to try unto thine fellow, what is hateful to thyself', is the foundation of Judaism." (Shab. 31a)
There are plenty of Arabs who are proud and grateful to currently be Israeli citizens and many others on the other side of the Greenline who would be too, if given the opportunity. The rationale of Rabbi Meir Kahane on this issue is evidently inaccurate.
Yet if keeping a group of people in a certain location would cause generations of bloodshed, it is morally wrong to assume that moving people in such a case would be ethnic cleansing. In fact not moving people could be dangerous. That part of it Rabbi Kahane got right.
As I mentioned years ago, the more this goes on, the worse the trend to radicalization would become. Violent indoctrination at Palestinian Arabic schools has caused a loss of so many who could have been civilization builders, but who now support terror. But it's not too late to find many innocents among them who can be saved, if offered a safe way out.
Moving masses of peoples is not always ethnic cleansing. If they could move people and divide a neighborhood often against the will of the residents there, to put in a highway, and for people who do not even live in that neighborhood, then why can't they do the same, to protect lives, on both sides of the ethnic divide? Certainly we should not destroy people's neighborhoods for no good reason. It's wrong to hurt the innocent in any way, if at all possible to avoid. But the point is, nations sometimes have done, and continue to do that, if they feel a compelling enough reason, for a sometimes esoteric ideal of "the greater good."
Ethnic cleansing, is the attempt to create ethnically homogeneous geographic areas through the deportation or forcible displacement of persons belonging to particular ethnic groups. Here, we are suggesting only filtering terrorists out of the populace via ideological markers and values that are too destructive for the common society of all ethnicities to bear in a given state. You can't kick out Jews or Arabs, but you can bring terrorists to justice.
More often than not, too many either foolish or hypocritical, and or antisemitic voices at the United Nations cried "wolf" and "apartheid" and "ethnic cleansing" in an effort to stop Israel from fixing this problem in a way that protects citizens of all ethnicities. How many nations protested that the Jews were being ethnically cleansed from Gush Katif two decades ago? If you don't know offhand, I'll give you a hint: you will not need a calculator to figure this one out...
But times are a changing, and Israel is and should get used to the idea of doing what is best for all their citizens of all ethnicities, without catering to the whims of anti semitic politicians protesting life saving policies at the U.N.
Peace depends upon Israel establishing it's own sense of a legal right to live in safety, and to demand it as a right before the United Nations. Don't be defined as "ethnic cleansers" by those who allowed it to actually occur in Syria for many decades until it laid the foundation for civil war there.
For the sake of the peace of all Israelis of all ethnicities, demand your rights and assert them. Even if ideological targeted relocation of groups of people becomes necessary to an extent.
Then you will be free to do the good in your heart for all your people, of all ethnicities, in the united Israel of tomorrow.
May it soon be so, by the grace of God.
