The conflict between Israel and Iran has grown more intense, raising serious legal questions under international law. Israel accuses Iran of backing Hamas, a Palestinian group behind attacks on Israeli soil, including the October 2023 assault that killed over 1,200 people. Iran’s financial and military support to Hamas, including weapons and training, has angered Israel, leading to retaliatory strikes on Iranian targets. International law prohibits states from aiding non-state groups in armed attacks against another state, putting Iran’s actions under scrutiny for breaching sovereignty and fueling regional tensions.
Israel’s military responses, such as airstrikes on Iranian nuclear sites and military bases in June 2025, seek to limit Iran’s influence and halt its nuclear program. These actions raise legal concerns under the United Nations Charter, which permits self-defense but requires proportionality and necessity. Israel claims its strikes are justified to protect its security, especially after Iran’s missile attacks in October 2024 and June 2025. Iran, however, argues that Israel’s actions violate its sovereignty, worsening the conflict and risking a broader war.
The United States supports Israel with significant military and financial aid, providing over $3 billion annually to bolster its defense capabilities. This assistance, governed by bilateral agreements, strengthens Israel’s military efforts but raises questions about U.S. accountability under international law. If U.S.-supplied weapons are used in disproportionate attacks, critics suggest it could implicate the U.S. in violations of humanitarian law, while supporters argue the aid is lawful support for an ally under threat.
The ongoing cycle of attacks between Israel and Iran threatens regional stability, with both nations claiming self-defense while accusing the other of aggression. International law calls for restraint and diplomatic efforts to avoid a full-scale war. The Security Council has pressed both countries to stop military actions and engage in dialogue, warning that continued escalation could lead to breaches of humanitarian protections and endanger regional peace.
