Iran has firmly rejected calls from France, Germany, and the UK to refrain from retaliatory actions against Israel following the assassination of Hamas leader Ismail Haniyeh in Tehran. Iranian President Masoud Pezeshkian stated that retaliation is a right of nations aimed at deterring future aggression, while Iranian officials criticized the Western request as lacking political logic and undermining international law. The U.S. and its European allies warned Iran of serious consequences should it proceed with military action, and have bolstered support for Israel by deploying military assets to the region. Despite these warnings, Iran has vowed to avenge Haniyeh's death, and tensions remain heightened amid the ongoing Israel-Hamas conflict. The Iranian government views the assassination as an infringement on its sovereignty and has called for Western nations to address Israel's actions in Gaza. This situation reflects the broader geopolitical struggle in the Middle East, as Iran, Hamas, and Hezbollah unite against perceived Israeli aggression.
