Yes, I was anticipating that picture to come up. It has been pointed out a thousand times why it is absurd to compare, but I'll go again. That pic was taken way before 9/11, and had nothing to do with Osama. It was taken when taliban and USA were fighting side by side against Soviets. After the taliban took power and established a crappy regime, US broke all relations with them. After Osama did 9/11, could you show me an instance of USA doing "diplomacy" with him and the ambassador greeting him with flowers?
If Modi actually did kill anybody, and USA "blacklisted" him as you say, then they would send navy seals with M-4s after him, not ambassadors with flowers. Try again.
It is really pathetic to see Pakistanis clutching at straws to draw a false equivalence between India and Pakistan, and pretending that there are Osamas in India. Nope - it happens only in Pakistan. Just because you want there to be a bad guy in India to feel good about your country, doesn't mean there actually is.
Bottom line - Pakistan's honoured guests are the world's scum. India's politicians are not.
