The threat of the Israeli–Palestinian conflict expanding from Gaza to other fronts increases significantly as the war escalates. The likelihood of direct Iranian military involvement remains highly improbable. Iran still prefers to rely on its proxies, although, in recent years, it has shown a growing willingness to conduct direct offensive operations against Israel from Syria using drones and rockets. While the interests of Iran and Hizballah are still inclined toward avoiding an all-out confrontation as much as possible, the potential for the convergence of fronts against Israel is gradually rising, involving Hamas from Gaza; Hizballah from Lebanon; and, potentially, pro-Iranian militias from Syria, Iraq, and Yemen. This reality necessitates Israel to decide whether it is advantageous to seize the current situation for a preemptive strike against Hizballah, which would reshape the Middle Eastern landscape in Gaza and Lebanon. While the Israeli military has prepared for the potential of a multi-front campaign for the last few years, dividing military efforts between the north and the south could jeopardize the primary endeavor against Hamas and the prospects of achieving strategic objectives against both Hamas and Hizballah.
