Israel and Hezbollah fought a war in 2006. The border has remained tense but largely quiet since then, with both sides wary of another major confrontation. But tensions have mounted. Hezbollah is committed, like its patron Iran, to Israel’s destruction and its leader, Hassan Nasrallah, regularly threatens Israel. Israel has complained about further provocations by Hezbollah, including over tents it says the group pitched on the Israeli side of the Blue Line — a demarcation set by the United Nations for the purpose of confirming the Israeli withdrawal from southern Lebanon when it ended an occupation in 2000. Israel has accused Iran of building an airport in southern Lebanon to be used as a launchpad for attacks against Israelis across the border, signaling a possible escalation in tensions between the regional foes. Do you think that Iran is acting against Israel?
