Who didn't do 9/11?
Who does Trump support?
Who was and still is the main target of the Neocons who ran 9/11?
Saudi Brig. Gen. Ahmed al-Asiri today told a group of US reporters that the Trump Administration has made promises to “significantly” increase US intelligence and military support for the kingdom against Iran, with a particular eye of fighting against the “Iran-backed” Shi’ites in Yemen.
...Trump is definitely on board with hostility against Iran, and Saudi officials say that Trump has invited Saudi Deputy Crown Prince Mohammed bin Salman to help him “make the plan for the Middle East.” Whatever other aspects this plan ends up having, Saudi input ensures it will mean US hostility toward Iran.
