you have at most 30 to 45 seconds to detect, launch and intercept any Shaheen series or Ababeel missile before it jettisons its first stage rocket booster. Even during that time, the missile keeps changing its trajectory (so good luck tracking it accurately) AND on top of that, it is already reaching speeds close to 5 km/s. After this short error prone period, you can launch every single interceptor missile in your arsenal and they won't be able to intercept it.
To accurately intercept a missile, speed, timing and accuracy is of the essence. So is it possible to intercept our missiles? theoretically, yes and that too maybe 1 out of 10. practically, highly doubtful.
