People like Lyndon Larouche & David Duke "pick on" all the organisations you cite, but we don't lend them any credibility. Rivero should be no exception. I don't have much time so am relying on a very quick google, but consider the following - far beyond simple "criticism of the Israeli govenment".
Rivero claims:
Israel controls America:
http://www.whatreallyhappened.com/briefing.html(He used to have the following quote in big bold print at the top of his site:
"I want to tell you something very clear, don't worry about American pressure on Israel, we, the Jewish people control America, and the Americans know it."
the only problem is that it's completely made up.
(Alternatively, Israel is blackmailing America):
http://www.whatreallyhappened.com/blackmail.htmlIsrael did/assisted 9/11:
http://www.whatreallyhappened.com/govknow.htmlIsrael is behind the Iraq war:
http://www.whatreallyhappened.com/offtowar.htmlUS Media is loyal to Israel (not America):
http://www.whatreallyhappened.com/litmus.html"Are ALL Al Qaeda really working for Israel?"
http://www.whatreallyhappened.com/fakealqaeda.htmland currently top of his page, Israel has a hand in the French riots
He describes Henry Makow (a blatant anti-semite & nasty misogynist to boot - if you don't believe me see his site
http://www.savethemales.ca/) as a "world class author":

He supports Ernst Zubdel (arch Holocaust denier):
http://www.whatreallyhappened.com/kangaroo.htmland the following is from Zundel's website (run by a supporter who calls the Holocaust a "blood libel"):
"The Internet, too, was alert and responsive to this tectonic political shift. Especially the Globe and Mail article, titled "Ernst Zundel: Civil Rights champion?" appeared on many prominent websites, for instance, on www.rense.com and www.whatreallyhappened.com - at the latter website with this editorial comment:
"Public opinion is beginning to turn towards Ernst and away from his persecutors. Ernst has not been charged with a crime, let alone convicted. The bottom line is that Ernst is being persecuted for questioning dogma, exactly the same crime for which Galileo was tortured. Truth needs no laws to support it. Throughout history, it is only lies that required the force of the courts to mandate belief.""

(2nd edit - I thought this was the case, but as this thread has been open several days I figured I was mistaken.
"Dandelion Books is a sister company to WhatReallyHappened, a noted conspiracy site famous that has been deemed inappropriate for use on DU because of it's anti-semitic commentary."

(edit - I'll bet anything that when he updates with the Jordan bomb story, he'll insinuate - or perhaps even flat out state - that Mossad was involved)
