A new Israel Defense Forces report reveals that since 2006, Israel's neighborhood has grown a lot more dangerous. According to the March 31 report, Hezbollah has been busy in southern Lebanon for the past five years. The terror group has built more than 500 bunkers armed with various weapons, 300 underground facilities, and 100 storage units for rockets, missiles, and other weapons. Many of these facilities are located near hospitals, homes, and schools.   

Uzi Rubin, Israel's foremost missile and rocket expert, told CBN News the threat to the Jewish state was "severe."  "Those bunkers are not in population centers just by mistake," Uzi Rubin noted.  

"The idea here is to attack Israeli population centers from Hezbollah population centers, to attack our population centers in order to terrorize and discourage us to fire from their population centers in order to use their own population as a human shield," he explained. 

Rubin said Hezbollah's arsenal has quadrupled since 2006 to more than 40,000 rockets and missiles. He explained that for Israel, there is a bigger concern than the number of weapons.. 

"Now, instead of spreading it around kilometers away from the target, they can put them within 500 meters of a target," Rubin explained. "Now they are becoming not just a terror threat, they are becoming a military threat."

This means Israel's national infrastructure, including power plants or Ben Gurion Airport in Tel Aviv, could become targets. 

With Hezbollah's rockets now capable of reaching central Israel, the northern border isn't the only danger zone. Add the rockets from Hamas in the south and all of Israel is in range of its Islamic enemies.
