Israel and Lebanon’s Hezbollah pulled back after an exchange of heavy fire over the weekend that briefly raised fears of an all-out war. But their decades-long conflict is far from over, regional tensions linked to the war in Gaza are still high, and it’s probably only a matter of time before another escalation. Hezbollah leader Hassan Nasrallah did not rule out another retaliatory attack over an Israeli airstrike last month that killed a top commander. Israeli Prime Minister Benjamin Netanyahu said “this is not the end of the story.”
