There should be a coordinated effort to deal with the problem. There are alternatives to a clampdown on terrorist activities by law enforcement agencies. They may be required in addition to strong legal action. Such alternatives include an end to commercial aircraft flights to certain areas or refusal of visas to travellers to those countries until a stronger effort is made to control terrorist activities. At the least. there should be armed guards on commercial air flights. particularly those within reach in the Middle East. As harsh as it may seem at the moment. there must be an end to capitulation to terrorist demands.
