Safety arguments are a red herring; terrorism will not be effectively prevented by the erection of the border fence. We need a proactive strategy that gathers intelligence and works with counterterrorism officials abroad to disrupt recruitment and training centers for terrorist groups.1 If some immigrants can slip through, so can some terrorists. At any rate, the 9/11 hijackers and other Al-Qaeda terrorists traditionally have not come through the Mexican border but rather from abroad and by airplanes or seaports, or they are homegrown radicals. Spending billions of dollars in a vain series of attempts to seal ourselves in an impenetrable fortress simply helps terrorists fulfill their goals of making us live in a culture of perpetual fear. As for drug trafficking, this problem is largely born of the tremendous market for it that still exists in the United States. If the demand dried up, so would the suppliers; on the other hand, if there is still an incredibly lucrative market, no fence will stop them from ferrying large amounts of drugs over the border, and most of the weapons the narcotics traffickers use actually come from the United States as well.2 We need to look to other solutions besides simplistic fences.  1 Bruguire, Jean-Louis.
