"The war against Takfiri terrorists is vital and determining, and we may declare public mobilization against them in the future," Nasrallah said during the meeting on Friday.
He noted that the conditions in Lebanon are as dangerous as those of the year 1982, and said, "The danger that is threatening us (and people, resistance and the region) is targeting Hezbollah's existence and it resembles the threat of the year 1982."
He said that everyone can take part in the mobilization to join the volunteer forces.
"From now on we will not remain silent and anyone standing against us … we will stare in his eyes and tell him that you are a traitor…," he added.
Last Saturday, Nasrallah lashed out at the US and the Israeli entity for making an instrumental use of Takfiri terrorism to undermine the Islamic nation.
"We are witnessing a new Nakba," Nasrallah said in a televised address.
"The Nakba of the Takfiri militants was first brought to the region by the British Zionist project, now it is the American Takfiri Zionist project, and America is using this to weaken the Ummah and tear it apart and to seize control of its capabilities," he added.
Every year on May 15, Palestinians all over the world hold demonstrations to commemorate Nakba Day, which marks the anniversary of the forcible eviction of hundreds of thousands of Palestinians from their homeland by Israelis and the creation of the Israeli regime in 1948.
On May 15, 1948, Israeli forces displaced some 700,000 Palestinians, forcing them to flee to different neighboring countries. Israeli soldiers also wiped nearly 500 Palestinian villages and towns off the map, leaving an estimated total of 4.7 million Palestinian refugees and their descendants dreaming of an eventual return to their ancestral homeland more than six decades later.
Nasrallah praised the "victory" in Qalamoun as a major achievement for Lebanon, Syria, and the entire region.
The battles there took place from "hilltop to hilltop and from valley to valley," he added.
Hezbollah, the Syrian army, and Syrian volunteer forces, as well as the locals in Qalamoun helped fighting the terrorists in the strategic area, he noted.
Referring to the major difficulties in the battle for Qalamoun, he said the high mountains and hills inside the area made the mop-up operation very difficult.
A total of around 300 square kilometers of the Syrian and Lebanese territory was retaken from the militants and some of their operation centers were also destroyed, Nasrallah added.
"The highest level of security was achieved for Syrian villages in Qalamoun and the same goes for Damascus-Homs road," he said, adding; however, that as long as the militants are present in border areas, such as in Arsal outskirts and some parts of Qalamoun, there would be risks.
Nasrallah said Hezbollah fighters have cut off the supply lines of the militants from Lebanon to Syria.
He further described attempts by certain entities to pit Hezbollah against the Lebanese army as "foolish".
The secretary general also criticized some Arab media for waging what he referred to as psychological warfare against Hezbollah. He added the media has overplayed the number of Hezbollah’s casualties.
"There have been thirteen Hezbollah martyrs in the battle so far," he stated.
Nasrallah also stressed that the media was trying to portray the Takfiri militants as revolutionaries while they are in fact terrorists.
Since the most recent Syria-Hezbollah joint operations about nearly two weeks ago, al-Nusra Front Takfiri militants had been using Qalamoun mountainous region for transferring weapons and reinforcements from Lebanon into Syria, where they have been engaged in terrorism operations against the government.
