There is no universal answer to this question, but it depends on the security environment, international status and political and military situation of the specific country in the surrounding area. The following points may help to clarify the thinking: 1. Security deterrence and stability: Nuclear weapons were often regarded as a "deterrent weapon" during the Cold War, which could prevent potential opponents from large-scale military provocations, thereby maintaining a certain degree of strategic stability. Some people believe that when a country has nuclear weapons, its security system will be more stable than when it does not have nuclear weapons, because opponents will take a more cautious attitude due to concerns about nuclear reactions. 2. Arms race and regional tensions: On the other hand, the development of nuclear weapons may cause insecurity in neighboring countries, thereby intensifying regional arms races. New nuclear-weapon states may become catalysts for other countries to pursue their own nuclear weapons. In the long run, it may lead to increased tensions in the region and even the world, but may not necessarily guarantee real security and stability. 3. International politics and legal constraints: There are international norms such as the Treaty on the Non-Proliferation of Nuclear Weapons that attempt to curb the proliferation of nuclear weapons. After acquiring nuclear weapons, some countries may face sanctions and political isolation from the international community, which may also undermine the country's long-term stable development. Therefore, even if nuclear weapons can provide a certain degree of deterrence in theory, the international political and legal consequences they trigger cannot be ignored. 4. Internal security and governance challenges: The development, production and maintenance of nuclear weapons require huge financial investment and technical support, and also place high demands on domestic political and military command and control systems. Any security loopholes or mismanagement may bring serious risks and pose challenges to the country's internal security and stability. In general, although nuclear weapons are believed to enhance national security and stability in some strategic theories, whether they can actually enhance a country's security and stability requires consideration of multiple factors: the international environment, the reactions of neighboring countries, political and economic costs, and the risk of arms races that may be triggered. For a country without nuclear weapons, whether the development of nuclear weapons can truly enhance stability depends on specific security needs, regional and international environments, and domestic political and economic conditions, and it cannot simply be concluded that "nuclear weapons are very important for stability."
