WASHINGTON (AFP) - New US rules tightening security checks on air travellers from 14 nations are ill-considered and unlikely to prove effective against future threats, a security expert said Monday. The Transportation Security Administration (TSA) said the new measures would include random enhanced checks on all international passengers flying into US airports, as well as compulsory stricter checks on those coming from or via 14 nations. The countries targeted include four nations that are US-designated state sponsors of terror, as well as a number of majority-Muslim or Arab countries. Edward Alden, a security expert with the Council on Foreign Relations denounced the measures as crude. I think that this is an ill-considered response that will do more harm to the United States than it does good, he said. Alden, the author of a book on US border policies after the September 11, 2001 attacks, pointed out that former president George W Bushs administration learned we needed to handle people individually because there were bad people coming from what we considered to be good countries. Taking a more nuanced approach led to a whole series of developments... these include the watchlists, information-sharing within the government and within allies, he noted. Any crude screening system based on nationality... (is) just going to be too easy for Al-Qaeda to defeat by recruiting elsewhere and the classic case of this was of course was the failed shoe bomber Richard Reid, said Alden. Meanwhile, Cubas official newspaper Gramma said the new US rules tightening security checks for airline passengers travelling from or through 14 countries, including Cuba, were the result of anti-terrorist paranoia. As part of its anti-terrorist paranoia, the United States strengthened security measures at its airports and has imposed tighter checks on passengers from 14 countries, including Cuba and others it accuses of supporting terrorism, the Communist Partys daily said.
