Terrorism and its solution in Pakistan and World?

Each and every human life is valuable, save the humanity.

Past few decade, Pakistan is under severe situation of terrorism and yet, no body knows who is involved. Someone takes the responsibility and who is/are behind them, no body knows. Nation does't need to know this, politician might know and let them play for their seat not for nation. I dont want to discuss the decision taken by the rulers, their impact, benefits or loss of being allies in war etc.

 In this era of technology, where world have established space station in outer space, exploring mars and thinking to establish human race on mars, technology is so advanced that we can forecast weather, clouds movement, chances of precipitation, this technology is so advanced that we are developing body organs with stem cells, where robots have replaced human and are more efficient, where artificial intelligence has solved many of our problems of strategic analysis, in this era where flood water can be monitored through satellite and can be told flow/min or hr etc. 

The technology is so advanced that we can locate position of person who has cell phone, as it is connected with satellite now, digital cameras have become so advanced that they record time and date of picture automatically with the picture, where cell phone talks can be recorded and monitored, where google glasses have been introduced to take picture with blink of an eye, where Apple has introduced GPS wrist watch, 

then

Why are we unable to tackle terrorism?

Terrorism in Pakistan, gun shots killing in Karachi city of Pakistan or any other part of the world are all dependent on supply of bullets, guns in simple words weapons etc. 

Have anyone tried to spot and check the weapon factories? Where do the negative people get weapons? If, the production of weapons and accessories stopped/banned atleast for 2 years, [except for army, police or rangers] and kept strong check on import/purchase/movement of weapons. Many of the problems can be tackled very easily. I think, in this era of technology, is it impossible to track weapons supply chain, if it is not impossible then why this is least focused area? I think no body is serious in that? The weapons dont come from sky. Purchasing a bullet can be hidden but purchase of thousands of bullets and no body knows, amazing?
