Some are framing this new policy as a blanket ban of certain groups. But this is another case of the B.D.S. movement spreading lies. The law gives the immigration authorities the option to ban individuals; it doesn’t mandate they do so.

Here is the truth: Similar procedures are common practice in most democratic countries. In the United States, for instance, the I-94W form (issued by the Department of Homeland Security) asks visitors if they have criminal records, if they were involved in espionage or if they helped Nazi Germany. If the answer to any of these questions is positive, that person may be refused entry. The same principles guided Israel’s decision.

Let me be absolutely clear: Israel is a thriving democracy and we welcome people who disagree with our policies. If you oppose the settlements and want to debate the future of Judea and Samaria, otherwise known as the West Bank, I welcome you to come and learn firsthand about the reality on the ground.

But the B.D.S. movement does not oppose specific Israeli policies or its current government. The goal is to wipe Israel off the map. Its website refers to a struggle happening “for nearly 70 years.” This timeline sends us back to 1948 and Israel’s inception, not to policy debates about borders stemming from the Six Day War in 1967. The conclusion is easy: The movement is not about the future of Judea and Samaria. It is about Tel Aviv and Haifa, and its leadership wants nothing short of our destruction.

The movement’s leaders don’t hide their goals, and some of their organizations even collaborate with convicted terrorists in their attempts to destroy Israel. Jewish Voice for Peace is one example. Last April, it featured Rasmea Odeh as a speaker at its national meeting. Ms. Odeh murdered innocent Israelis in 1969. She is a convicted terrorist found guilty of immigration fraud by an American court after concealing her role in two bombings in Israel. Yet the executive director of Jewish Voice for Peace said that the group was “honored to hear from her.”

While B.D.S. activists try to hide behind the mask of “human rights,” more and more people understand the truth: The movement is anti-Israel and anti-peace. Several American states have passed anti-B.D.S. laws and resolutions. Cities in Spain, Germany and other European countries have also acted against the movement. These places refuse to accept bids for contracts from companies supporting the movement, and some stopped doing business with European banks involved in the campaign. They understand that opposing B.D.S. means standing up for peace.

Israel’s decision to expose those out to hurt us sends a clear message: Those who seek our destruction are not welcome in our home. Any other country in a similar situation would do the same.
