Even the Saudis wanted Netanyahu to address Congress:
“I am very glad of Netanyahu’s firm stance and [his decision] to speak against the nuclear agreement at the American Congress, despite the Obama administration’s anger and fury,” wrote the Saudi. “I believe that Netanyahu’s conduct will serve our interests, the people of the Gulf, much more than the foolish behavior of one of the worst American presidents.” -- Dr. Al-Faraj - Saudi daily newspaper Al-Jazirah on Monday
"The foolish behavior of one of the worst American presidents"
That is nothing to brag about. Saudi Arabia has one of the worst human rights issues in the world, not even mentioning that they are one of the biggest supporters of terrorism. Them backing Netanyahu doesn't make it right.
