Bhai....significance....
CAS.....He's the same man, of the same force (PAF), which came out on top last year....
Location of the visit.....Occupied Kashmir in front with disputed Ladakh nearby, all within flying distance....
JF-17s....chinese platforms being shown in the video, again the same platform which did well last year as well...
Coupled with all this....
CAS' statement signifies that we are keeping a close watch on whatever is going on in the northern regions...there is also an obvious probability that IAF has taken the necessary safeguards in case there is some activity from Pakistan's side, maybe PAF has already countered THAT IAF buildup......
actually all this...visits, statements, PR....it increases the complexities for the other side.....they have to dig around alot in order to find out what PAF CAS really meant and what message Pakistan as a country wants to send.
