Dr. Ephraim Herrera, an expert on Islam and jihad, spoke to Arutz Sheva about the threat radical Islam poses to the world and recent developments in the fight against terror.

He began by speaking about Hezbollah's top military commander Mustafa Badreddine, who was killed in a mysterious explosion last Thursday night near Damascus. He was the successor of Imad Mughniyeh.

Badreddine began his terrorist career in the Palestinian Authority's (PA) leading Fatah faction, and was among the founders of the Lebanese terrorist group Hezbollah, a Shi'ite proxy of Iran.

Outlining the terrorist's career, Herrera noted he was responsible for an attack on US and French army barracks in Beirut back in 1983, which left hundreds dead and wounded and caused the US and France to pull their troops out of Lebanon.

Then he hit the US and French embassies in Kuwait, where he was arrested and condemned to death until Iraqi dictator Saddam Hussein invaded the country and freed him, at which point he returned to Hezbollah.

When asked who was responsible for Badreddine's death, Herrera pointed out that Hezbollah claimed Sunni factions fighting in Syria were responsible, although he noted there is only one guilty party as far as the terror group is concerned.

"For Hezbollah the source of all these attacks against Hezbollah is Israel," he said. "They think Israel is guilty."

However, he reasons that Hezbollah will not attack and cause a Third Lebanon War at this point in time.

In making that prediction, he explained Hezbollah is weakened after the damage they took in the 2006 Second Lebanon War and their heavy losses in the Syrian war propping up Bashar al-Assad's regime. He also noted that Lebanese banks have closed the accounts of Hezbollah members fearing international repercussions.

At most, he warns the terrorists may attack Jewish targets abroad.

Turning his attention to Europe, he explained how the continent has rapidly become Muslim. In Britain the Muslim population has doubled in the last 15 years, and in Germany over 1 million Muslims arrived last year.

"When they come they come with their values, and their values are Islamic values," he warned, citing a recent poll showing that around 40% of Europe's Muslims want Sharia Islamic law in regions where they are a majority.

The European public is waking up to the threat, Hererra assesed, but the governments are not. Slowly that will change as far-right parties gain more support, according to the expert.
