The introduction of the United Nations Convention on the Rights of Persons with Disabilities (CRPD) sets up the starting point for the protection of the rights of persons with disabilities in the International Human Rights Law (IHRL) system. Nevertheless, as the largest definable disadvantaged group on the planet, quandaries still exist for States and the public sector in general to eliminate the discrimination and invasion of disability rights in society. Currently, even though there has been significant progress in recognizing and protecting disabled peoples rights, discrimination, access to justice and legal remedies, and the ineffective application of international treaties are still common phenomena in various social aspects. This paper aims to analyze the problems and weaknesses in the current international disability law and propose recommendations to strengthen the protection of disability rights both in peacetime and during armed conflict pursuant to International Humanitarian Law(IHL). In addition, this paper will further examine several state practices even though many nations have established policies and measures to protect disability rights, potentials for further improvement remain, such as the enactment and monitoring of comprehensive disability rights legislation as well as the popularization of knowledge. To achieve the ideal result, governments, civil society groups, individuals, and the international community shall actively cooperate to effectively safeguard the rights of persons with disabilities, proposing initiatives founded on a thorough and inclusive knowledge of disability rights, dedication to eradicating prejudice, advancing equality of opportunity, and ensuring that everyone has access to the justice and remedies.
