Shooting down your own satellite isn't an "issue of national security."
And the question isn't whether it is permissible, but rather was it an obvious opportunistic move? The answer to the latter is yes to pretty much all of the outside observers.
They shot the satellite with a "missile". And it was a demonstration of what we would do when a spy satellite hovers above us during "wartime". The PM in his address clearly said that this successful test makes "India" more "secure". Considering all this, it pretty much qualifies to be a national security issue to me.
