15 of the 19 9/11 hijackers were from Saudi Arabia. The current ban would have done nothing to prevent them from coming here.
I could see a ban making some sense, but any ban that leaves out Pakistan, UAE and Saudi Arabia has deficiencies so glaring that it would never be worth the suffering caused.
Prior to 9/11, the all-time US terrorist record was the Oklahoma City bombing, by two white dudes. Divide out the number of deaths in each attack by the number of people directly involved in the attacks, and you reach comparable numbers.
Considering your views towards Muslims and willingness to ignore vast amounts of domestic terrorism, it seems like the goals of the 9/11 hijackers has been acheived.
9/11 is a valid date to start from because a large part of its shock value is that for the most part of post WW2 America, there weren't any foreign attacks on American soil. 9/11 was the anomaly, meant to provoke US outrage and further our violence against the middle East, convincing more young people that the US was an agressor and that they were the righteous. Clearly, these people are not righteous, but neither were we.
