scrutinizing terror

because one Nigerian man (who joined a Yemeni group while he was staying in London) attempted to set off a bomb on a plane over Michigan, all 154 million Nigerians will now be subject to special security measures. bringing this closer to home, since the Oklahoma City Bomber and his assistant were born in New York and Michigan, the citizens of those states should also come under increased scrutiny. while i can almost follow this puerile logic, i am amazed at the audacity of including Cuba on the list of "suspect" countries, since the United States has engaged in covert terrorist attacks against Cuba for over forty years, including shooting down a Cuban airplane (killing all 73 occupants) in 1972 under the orders of then President Nixon. so this set me to wondering just how many countries have legitimate cause to think of United States citizens with "increased scrutiny". surely Iran, since i have just learned that President Obama has continued a Bush Administration policy of appropriating 400 million dollars annually to the covert internal disruption of the Iranian government (while offering a "new beginning" in his well-publicized speech last year). is that not state-sponsored terror? is making a list of countries we can't trust part of the fight AGAINST terror or part of the fight FOR it?
