Don't be fooled. Any Republican/conservative would have a similar if not more fitting policy on the war on terrorism. From a more conservative administration, we will see our borders being protected, Saudi Arabia exposed for the fruad they are, and curtailing immigration from Islamic countries. The goal is how do we get a more conservative person in the White House.
I understand your concern for protecting our borders, at the same time, 99.9 % of those who cross the border are not a national security threat. At the same time, I do not believe it would hurt the Administration to step up on more border security.
As for Saudi Arabia, I would like to believe that they are still a solid ally. With the royal family being as large as it is, it seems that there are bound to be a couple duds in the bunch. At the same time, I wouldn't be surprised if the Royal Family is unofficially funneling money to terrorist organizations in their country in order to squelch dissent, or an all-out revolt within their kingdom.
