s in front of him, not realizing that another was sitting behind him,  read the report, naming Lewin's probable killer as Satam al Suqami, a 25-year-old Saudi.

Reports of Lewin struggling with four terrorists provided some solace to his inner circle.

 He fought back with his own bare hands,  Greenberg said defiantly of his friend, a  trained killer, armed with only a blackberry and laptop.  The 5-foot-9 ex-commando weighed  180 pounds of rock steel. 

He is believed to have been killed some 20 minutes before the plane struck the WTC, according to Greenberg.  They surrounded him - his throat was slashed and dead before they hit the tower.

He friend says Lewin would be sickened to see that 25 years after the deadliest attack on American soil the unthinkable tragedy has been recast to vilify the US and prop up terrorist ideology.

Lewin would rail against the memory of 9/11 tragically morphing into an ideological issue that's led to the next generation idolizing arch terrorist Osama bin Laden while blaming the US for bringing it onto itself, said Greenberg, 62.

 Danny would be incensed not just over the political divisiveness today,  said the pal,  but of how it's been sanitized.  Watered-down language, like the  events of 9/11,  outrage Greenberg.  It's not a TV miniseries - it was a vicious and shocking attack on civilians.

The  hero commando  was considered to have  transformed the internet,  according to a book about the rising star.

Lewin would have gone on  to be a household name if he lived,  claimed Greenberg.  Along the lines of Elon Musk, Mark Zuckerberg and Sergei Brin.

 I always said to Danny,  You're either going to be the next Bill Gates or you're going to be the next prime minister of Israel - or both,  mused Greenberg.

Greenberg wants people to know of his friend's heroism.  It's using his story to inspire others to take risks in life. 

To see the truth about 9/11 and origins of terror twisted would have shaken Lewin to his core.

 Danny was not PC, but he was so respectful of other humans of every creed and religion,  said Greenberg.  But he would call it like it is - he would make a sharp distinction between Islam and radical Islam.

 He knows that's the malignant ideology that murdered him.
