see every missile test is monitored all around the world, your secret missile test will be detected by not only India, it will be detected by many country . no missile test will remain secret.
please if you can answer , answer with logic
We had nukes way before 1998 that nobody knew about. If they cannot find out about nuke tests, I don't see why missile tests need necessarily be found out. Why would Pakistan and India have a treaty of telling each other of upcoming ballistic missile tests, then?
Just do a google search on secret missile tests. This one came up quick. BBC NEWS | Middle East | Israeli secret footage blunder (It would have been a secret had this blunder not happened).
I don't know where you're getting the idea that a missile test will never be a secret.
I am not sure what you consider logical, but is this logical enough for you?
