America should not be stupid to sell smart bombs or any weapons to Saudi Arabia whose savages attacked America on 9/11. Saudi Arabia is also the Head and Financier of the Islamist-Jihadist Terrorist tentacles around the world that have committed atrocities against humanity. Their sins are well documented in "Secrets of the Kingdom"  by Gerald Posner, "Jihad Incorporated"  by Steven Emerson, "Hatred's Kingdom"  by Dore Gold and "Preachers of Hate"  by Kenneth R. Timmerman. These books are powerful and a Must Read.
