If Pakistan did not have nukes it would be divided at least 4 parts today, not all countries in the south Asian region have the luxury of being India's favourite pet, you should be grateful to Pakistan for its taking the burden off Bangladesh by being on India's bad side and its resources pointed at us, for if there was no Pakistan, you would be India's worst enemy especially with this right wing nationalistic regime, your economy is growing at faster rate amongst SAARC countries, which means your also a threat to their wishful hegemony in the region.. don't be so naïve to think you will keep enjoying 'these' warm relations with India.
The only problem with Pakistan is it's corruption went unchecked for so long, we should of had an economy at least 2.5 its current size today, but atlas that's not the case.. our compromised establishment would rather see us fail then prosper..
BD is aware that India does not want an economically strong BD as it threatens the very existence of their state in their current form.
That is why BD is actually in the middle of a massive arms buildup. India will just have to learn with a strong BD
