Prime Minister Binyamin Netanyahu met with leaders of the Jewish Federations of North America on Tuesday, a day after addressing the UN General Assembly in New York where he argued the Hamas terror group is just like Islamic State (ISIS).

"Every time I come to the UN I try to tell the truth as it is," Netanyahu said. During his address Netanyahu showed a picture of Hamas terrorists firing a rocket near small children.

"But here's a picture I didn't show in the UN yesterday. This is an impending execution. But this isn't ISIS, this is Hamas. And during the recent fighting in Gaza, right around the time that ISIS was doing its grisly deeds, Hamas executed dozens of Palestinians just to impose fear and force the population of Gaza into submission," said Netanyahu.

The Hamas "killing spree" of those it accused of "collaboration" with Israel led to outrage from the Palestinian Authority (PA), partially due perhaps to rumors that Hamas was using the claims to liquidate Fatah rivals.

The White House on Monday criticized Netanyahu's comparison of the two terrorist organizations Hamas and ISIS, to which Netanyahu said Tuesday "it's true there are some differences between Hamas and ISIS - for example ISIS beheads people and Hamas puts a bullet in the back of their heads. But to the victims, and the victims' families, the horror is the same."

"The point I was trying to make yesterday and I'm making today is that we are faced with a world-wide network of militant Islamists, groups and regimes. It's not that they have a common war-room. They have war-rooms against each other because all of them wish to dominate first the region in which they are in and then ultimately the entire world," continued the prime minister.

"But they all share this fanatic ideology; they all have not only unbridled ambitions but also savage methods. And the more they have the capability to realize their ambitions, the more they'll unleash their pent-up aggression against our common civilizations," added Netanyahu. "We have to stop ISIS, defeat ISIS, but we have to prevent Iran from getting the capability to produce nuclear weapons."

Netanyahu is set to meet with UN Secretary General Ban Ki-Moon and speak to world media later on Tuesday, and on Wednesday to meet with US President Barack Obama.

In that meeting, a senior source with Netanyahu's entourage revealed to Arutz Sheva that Netanyahu plans to raise the release of Jonathan Pollard, now in his 29th year of incarceration in an American jail cell on charges of spying for Israel.
