There's a difference between an opposition/politician warmonger and a warmonger head of state. Many leaders use inflammatory damaging rhetoric during elections, but few take it too far and start acting on it (Saddam, Hitler, Putin etc). Those who act on it usually don't have good ends. Even with all the stuff he says, I doubt he's stupid enough to actually declare war on anyone. Pulwama attack was an highly extraordinary event. He said what he said and did a small airstrike. Nations have gone to war for much less.
