Yes, the Universal Declaration of Human Rights (UDHR) applies to all human beings, including Palestinians. The UDHR is based on the principle of universality, meaning that the rights and freedoms it outlines are applicable to everyone, everywhere, without distinction of any kind. Here are some key points regarding its application:

1. Universal Application: Article 2 explicitly states that everyone is entitled to all the rights and freedoms set forth in the Declaration, without distinction of any kind, such as race, colour, sex, language, religion, political or other opinion, national or social origin, property, birth, or other status.

2. No Exceptions for Nationality or Territory: Further, it specifies that no distinction shall be made on the basis of the political, jurisdictional or international status of the country or territory to which a person belongs, whether it be independent, trust, non-self-governing or under any other limitation of sovereignty. This means that Palestinians, regardless of their territorial or political status, are entitled to these rights.

3. Rights to Self-Determination and Human Dignity: Many of the rights outlined, like the right to life, liberty, security of person, freedom from torture, equality before the law, and the rights to privacy, movement, nationality, and asylum, directly relate to issues often discussed in the context of Palestinian territories.

4. Implementation Challenges: While the UDHR sets out a common standard of achievements for all peoples and all nations, the actual enforcement and protection of these rights depend on national governments, international bodies, and sometimes non-governmental organizations. The situation in any conflict area, including regions involving Palestinian populations, often shows the gap between these rights in theory and their practical implementation.

5. International Responsibility: The international community, including states and organizations like the United Nations, has responsibilities to promote and protect these rights. This includes ensuring that all parties in any conflict adhere to international human rights law and humanitarian law.

The application of human rights in conflict zones like the Palestinian territories often becomes a focal point in international dialogue, with advocacy groups and human rights organizations frequently calling for adherence to these universal standards. However, the practical realization of these rights can be complex, involving issues of international law, diplomacy, and security concerns.
