How can you say that Are you waiting for them to drop bombs on us than only IAF should retaliate, it's Indian airspace & any plane crossing it is an intrusion weather armed or not.
A brash attitude like this is thankfully not seen in professional forces like the IAF..
Aircraft about to violate airspace(5-10 min out and inside no-mans land) are warned on guard channels first.
If they do not turn back .. interceptors are scrambled...
In this case .. PAF aircraft heard the warning.. and turned back..
all in a days work for both sides.
