re: What would Islamists terrorists attack in America that is supposedly on Friday?

Shabbat starts Friday at sundown, which means there will be large gatherings of Jews heading to or participating at Synagogues all over. At least in Houston, the Conservative sect synagogues have had security fencing and a least a security guard even in normal times. Those liberal (reform) Jews up in the Woodlands better understand they are the softest target in the area.
