Firstly, welcome to the forum!
What meeting are you inferring to?
The government of India
is the democratically elected representative of all Indians.
Indian GDP is almost $2 trillion USD ($1.848 trillion USD to be exact), so $80 billion over 5 years is peanuts for India. Secondly, unlike Pakistan, when we buy weapons, we strip them of any gear which comes with strings attached. We refuse to sign onto agreements such as the Logistics Support Agreement and other such deals which restrict us to the US tune. This means that many weapons we buy, such as the recent C-130s or P-8Is, come stripped of communications and other such gear. We simply replace those components with our own or European and Israeli gear. Our weapons markets are also a lot more diverse than Pakistan. Majority of our weapons come from Europe, Israel and Russia, not the US.
Again, India has not signed onto any deals with the US which makes it an American "poodle" like Pakistan. We openly oppose the US on the international stage where our interests diverge, such as Syria and Iran, and openly work with the US where our interests converge, such as Afghanistan.
Secondly, it is your misgiving that India gets aid from the US. India is not Pakistan so it is useless to compare the two.
India can well afford it's weapons. Here is the difference between India and Pakistan illustrated:
Pakistan's GDP is $211 billion while India's is $1.848 trillion. That means India can outspend Pakistan based on a GDP which is 9 times the size of Pakistan's economy. The question of charity does not arise here!
Ajmal Kasab is an illiterate person and the name "Kasab" is not an official name, it is a loose name to describe him. That said, since you know of Punjab so much, you'll know that poor peasants like Ajmal Kasab largely do not have registered or documented names per se. The rural peasants are largely given names through word of mouth, and have little papers to show for it. That said, as far as Indians are concerned, it is not just Kasab, but your very own Hafeez Saaed and countless others who openly celebrate the Mumbai attacks and talk of more to come, so we are fully convinced that Pakistanis are involved. If you wish to believe in conspiracy theories, sure, you may well do so, but your country will continue to suffer the consequences on international platforms. It is better yet to introspect and call out your military rulers to clean up their act. Conspiracy theories only look good inside Pakistan, not outside.
Again, that's a wild conspiracy theory and it is easy to come up with them sitting behind a computer. However, if you truly believe it is so, than there is nothing stopping you from taking a trip down to Mayanmar and proving us wrong.
