Saudi Arabia put up a blockade (with an Arab coalition support) of Qatar for a number of reasons[1], one of which being Al Jazeera’s incendiary (in their opinion) coverage of sensitive topics within the Arab world during the Arab Spring. Saudi Arabia wanted the channel shut down.
They never intended to invade and the biggest factor was Qatar’s relationship with Iran (Saudi Arabia’s arch rival).
The link with AIPAC? Why would the Saudis, who have no formal diplomatic relations with Israel care?
Sounds like a complete made up conspiracy theory.
Additionally, the blockade you speak of was set up in retaliation for Qatar refusing to make a sucker's solo investment in the floundering Kushner real estate debacle.
