It is difficult to predict exactly what would happen if Iran were to attack Israel, but the situation could potentially spiral out of control and have far-reaching consequences. The Iranian-Israeli feud has been heating up in recent years due to Irans advancing nuclear program and its campaign to funnel weapons to allied proxies in Lebanon, Syria, and Gaza. Iran has vowed that Israeli reprisal attacks, which have killed thousands of people in Gaza, will be answered by Irans so-called axis of resistance, which includes anti-Israeli and anti-Western groups in Lebanon, Syria, Iraq, Afghanistan, and Yemen. If Iran were to escalate the conflict, Israel would be forced to retaliate, leading to a potentially devastating full-scale war. While it is not likely that Iran would launch direct attacks against Israel, the possibility of a regional conflagration is real. The main risk is that Iran could push its allies in Lebanon, particularly Hezbollah, to open a new front against Israel in the north.
