It is important to observe that Pakistan is facing the biggest challenge since Independence. The enemy is invisible and thus very hard to follow. The consecutive attacks on Fazlur Rehman has left many shocked and raised many questions for near future. Is any political figure really safe in Pakistan now? Terrorism can only be eradicated if Pakistan takes advantage of all available options and provides security to political figures at first. More assassinations targeting political figures will disturb the stability of Pakistan even more. This will only give a freehand to the anarchy in the country. ALI HAMDANI, Texas, April 1
