No Saudi citizen I know hates America, heck they've embraced the American culture with awe and are the 4th largest student population in the US. American Fast food, American cars, etc are cherished and many American companies have flourished because of their establishments in Saudi Arabia.
Assumptions are harmful. Iranians on the other hand have a genuine reason to hate the US. Iran funds Hezbollah which have attached American interests in the past. It was Iranian-aligned militia that wrecked the American army in many battles in Iraq.
