While the Israeli military has adjusted its priority among different fronts according to changing situation in the region, the Lebanese border is still secured, a senior officer with the army's Northern Command told Xinhua on Thursday.

The change of focus to borders with Egypt and Syria "affects the allocation of resources and troops, but I don't see any change here. (Lebanese border defense) remains strong," said the officer, who requested anonymity because of the sensitivity of the issue.

Top Israeli political and defense officials have repeatedly expressed their concerns over the growing lawlessness in Egypt's Sinai Peninsula following the ouster of former Egyptian president Hosni Mubarak early last year, with massive amounts of weapons making their way into the peninsula virtually unimpeded along with a host of militant groups.

Meanwhile, the Israel Defense Forces (IDF) announced last week that it is boosting defense systems along the border with Syria in preparation for possible militant attacks and waves of Syrian refugees.

In comparison, the Lebanese front has been mostly quiet since the Second Lebanon War in 2006, a month-long conflict resulting in the deaths of some 1,200 Lebanese and 160 Israeli troops and civilians.

Standing on a platform overlooking the hilly border, the officer said that it is not in Hezbollah's interests to reignite the area now.

"But interests can change overnight," he said, as the Shiite militant group is building arms cache and training personnel, getting ready for the next round. Israeli military estimates say that Hezbollah has amassed some 40,000 Katyusha, Grad rockets, as well as Scud and other short and medium-range missiles.

The army is concerned over the possibility of Hezbollah joining Iran in any potential war with Israel.

"The hand of Iran is here. It has a lot of influence on Hezbollah," the officer said.

Israel and the United States believe Iran is operating a clandestine military nuclear weaponization program, under the ruse of medical research and power generation. Israel considers a nuclear armed Iran as an existential threat, particularly in light of repeated statements by its leaders to destroy the Jewish State.

An Iraninan commander last week vowed to attack Israel if necessary, and implied that the Islamic republic's "security alignment" Hezbollah was capable of damaging Israel more than ever.

In the event of another major conflict in the northern border, "The IDF is prepared ... to hit Hezbollah decisively and quickly," the Israeli army source said. His words echoed Chief of Staff Lt. Gen. Benny Gantz, who had said in April that the army will be able to deal with rocket attacks from Lebanon.

"I cannot promise that missiles will not fall here. Many will fall. It will not be a simple war -- for both the front and the rear. But I don't recommend anyone to test us. When (Hezbollah's Secretary General Hassan) Nasrallah leaves the bunker he's very worried -- for a good reason. He saw what happened to Lebanon the last time," Gantz said, referring to the 2006 Lebanon war, when Israeli warplanes hammered Lebanon's civilian infrastructure in response to the firing of thousands of rockets at northern Israel.
