India and Pakistan are both nuclear armed. However, when it comes to armies, India has the 3rd largest army in the world; Pakistan ranks at number 7. When it comes to most powerful militaries in the world, India ranks at number 4; Pakistan is nowhere in top 10.
India is also the 5th largest Military spender in the world, Pakistan is not in top 15.
So yes, on paper, India is stronger than Pakistan; and is likely to win any war.
But again, we’re talking in hypothetical. And hopefully, a war-like situation will never come between the two countries.
