Flame baiting - are you? Let's see - China's military spending is $119 Billion, Japan's is at $54.5 Billion and SK at $27.6 Billion - together they make up about 68% of China - think that's nothing? Well, the USAs military spending is about $700 Billion - or 6 times that of China - and you think you can match the USA, but Japan and SK cannot match you?
So, you just have "common interests" with NK and Pakistan? What are those? Scaring your neighbors? Targeting their citizens?
As for "Muslim" countries like Malaysia and Indonesia accepting "Hindu" India - they are already doing naval and airforce exercises with India - and not just once - several times in the last few years. Actually for them, "Hindu" and Muslim" are not as much of a divider as "China" and "non-China" is. How many disputes do the Chinese have with Malaysia and Indonesia? too many to count. How many does India have with them? None. You know when shit starts flying from China, who they would rather have in their corner? Not Pakistan (their "Muslim" brethern) but "Hindu" India.
Doubting India's nuke capabilities is fine. Do you doubt Pakistan's too? Then again, why should you? PRC supplied them with the fissile material, if not the bomb itself. So, no doubts there right? As for Indian Nukes - I am pretty sure that they will work if needed - like ISRO's missiles will work fine too ...
I hope it NEVER comes to that though. I work with Chinese colleagues and friends. And I LOVE Chinese food.
