Strike at their command centres is NOT NUKING entire population of Indian!!

47:4 If you meet the disbelievers in battle, then, strike at their Command centres. Until you have subdued them, then, bind them firmly. And thereafter, must be an act of kindness or ransom when the battle lays down its weapons. And if God willed, He could indeed punish them Himself, but that He may let you test one by means of another (as to which nation remains vigilant.) And, as for those who are slain in the Cause of God, He does not renders their actions vain.

Self defence and reasoned response to their transgressions or mass murder of innocents because they are 'attacking' muslims?

When did we become khawarij?
