Fact Check: Was Israel's Attack on Iran Legal?
What We Know
On June 13, 2025, Israel launched "Operation Rising Lion," targeting various military and nuclear facilities in Iran, citing the need to eliminate an imminent threat to its national security (source-1). Israeli officials, including the Prime Minister and Defense Minister, characterized the operation as a necessary act of self-defense against Iran's advancing nuclear capabilities, which they perceived as an existential threat (source-1). The International Atomic Energy Agency (IAEA) had recently reported that Iran was in breach of its non-proliferation obligations, further escalating tensions (source-1).
The legality of Israel's actions is debated within the framework of international law, particularly under Article 51 of the UN Charter, which allows for self-defense in response to an armed attack. Some legal scholars argue that Israel's actions were justified as anticipatory self-defense due to the imminent threat posed by Iran (source-2). However, critics argue that the attack constituted a violation of Iran's sovereignty and international law, as the concept of "imminent threat" is subject to interpretation and debate (source-3).
Analysis
The claim regarding the legality of Israel's attack on Iran hinges on the interpretation of self-defense under international law. Proponents of Israel's actions argue that the country was acting within its rights to preemptively defend itself against an imminent threat, citing the historical context of hostility between the two nations and Iran's ongoing nuclear ambitions (source-1). The argument for anticipatory self-defense is supported by various international legal principles, including the Caroline test, which allows for pre-emptive action under certain conditions (source-1).
Conversely, critics highlight that the lack of a formal declaration of armed conflict and the absence of an actual armed attack at the time of Israel's strikes raise significant legal concerns. The International Commission of Jurists (ICJ) has condemned the attack as a violation of international law, arguing that it threatens peace and security (source-3). Furthermore, the interpretation of what constitutes an "imminent" threat is contentious, with some legal experts asserting that Israel's actions do not meet the necessary criteria for self-defense under international law (source-4).
The sources used in this analysis vary in credibility and perspective. Scholarly articles and legal analyses provide a nuanced view of the situation, while media reports may reflect biases based on national interests. For instance, the ICJ's condemnation carries significant weight in international law, while opinions from commentators may reflect more subjective interpretations (source-2, source-5).
Conclusion
The claim that Israel's attack on Iran was legal is Partially True. While there are arguments supporting the legality of the attack under the premise of anticipatory self-defense, significant legal and ethical questions remain. The lack of a clear armed conflict and the contentious nature of the "imminent threat" concept complicate the assertion of legality. Thus, while some interpretations of international law may justify Israel's actions, others firmly oppose them, highlighting the complexities and gaps in international legal frameworks regarding state conduct in conflict.
