Submitted to: Special Committee on the United Nations Charter
From: The State of Japan
Delegate name: Jada Wynn
Subject: Clarification of Article 51
The purpose of Article 51 is to give countries the ground basis of what using self defense and what the procedures should be, but there is a concern about some of the holes in the article that don’t give much clarification, which led to some potential loopholes. In a Security Council report regarding the increasing use of Article 51, it mentions how the debates regarding the interpretation of Article 51 have intensified over the last decade, but particularly the US and its allies have increasingly relied on the expansive “unwilling or unable” doctrine to justify military measures on the territory of other states, including counter-terrorism operations. These have led to attacks with a multitude of controversies, such as Israel’s September 9th strikes against Hamas, and the Iran nuclear facilities attacks made by the United States, both claiming that it was for self-defense, Israel claiming that it was in response to Hamas actions on October 9th and its ongoing attacks, while the United States claims that Iran was not negotiating in good faith, which resulted to the US striking down the potential threat before the enemy could do anything. With this issue of vagueness and the many interpretations for Article 51, countries will be able to find potential loopholes around Article 51 and use it in bad faith. Article 51 needs to add more clarification about what issues the right to self defense and erase the vagueness surrounding Article 51 in order to prevent countries using it in bad faith.
In terms of Japan using Article 51, the country has no plans of issuing the article at all, in fact, the country renounces any use of violence and starting wars. This statement can be seen in the Constitution of Japan, under Article 9, stating, “Aspiring sincerely to an international peace based on justice and order, the Japanese people forever renounce war as a sovereign right of the nation and the threat or use of force as means of settling international disputes…” While the State of Japan renounces war, the country still understands the potential threats looming around the country. In an overview of Japan’s defense force, there are concerns about Japan’s neighboring countries’ military threat and what challenges Japan might face, such as Russia’s aggression against Ukraine and North Korea becoming an even more imminent threat than before with its military advancements. To conclude, Japan wants to keep peace and avoid violence, but the country will have no problem defending itself when such force is needed.
The best way to approach this issue regarding the vagueness of Article 51 is further specify what issues the right to self defense, such as self defense can only be issued if there is an active threat from an enemy country or said enemy country has already attacked the country first, and there was no previous foul play coming from the country issuing Article 51. This is to prevent instigators constantly pressuring enemy countries until the enemy attacks to issue Article 51 and countries using the right to defend themselves before the enemy country can even attack. This one specification can help close the many loopholes and vagueness in the article. While Article 51 has good intentions surrounding it, the vagueness in the article is causing many issues; there needs to be better clarification in Article 51.
In conclusion, the State of Japan is happy to work with anyone in order to help improve Article 51. Japan strongly encourages adding more specifications in the article when addressing self defense and the context of the situation to enforce Article 51. It is very important to avoid having countries using Article 51 in poor taste to target certain countries for selfish reasons instead of the main purpose, protecting the country and its people against a former threat. Japan will be strongly advocating for further specifications for Article 51 so that it can still be used; Article 51 has some holes, yes, but it is still a good general basis on policies and regulations on the topic of attacking another country and defending itself. These holes in Article 51 are detrimental to the article’s purpose and must be addressed immediately in the committee before further damage is committed.
