Well here are a few points for you : 1) Pakistan is too big a country, so a military response is unthinkable! At a population of 170 million its roughly 6 times the size of Afghanistan. So imagine 6 times the economic commitment, 6 times the number of troops deployed and more importantly 6 times the casualties then in Afghanistan, I don't think the govt would wanna venture there.
Conventional military can be overthrown in days but to occupy such a country, which as a matter of fact is more hostile towards the Americans then even Afghanistan, would be disastrous! 2) China factor: China uses Pakistan as a balancing force to India, a rouge proxy state to pressurize India. Any void created by the US and an American misadventure, will be surely exploited by the Chinese to increase its sphere of influence in that region 3) Oil corridor : surely the oil in the middle east is gonna run out in our lifetime, so the only source of untapped oil lies in central asia and there are 4 power hungry countries namely America, Russia, China and India competing for it.
For America (considering Iran is hostile) the only way out is through Afghanistan and Pakistan 4) war in Afghanistan: the US is in Afghanistan, and cant withdraw and the only way again to support US troops is through Pakistan unless there is a regime change in Iran 5) Weapons sales : and we could give free weapons to Pakistan (which cannot afford them) but we could always charge India for buying weapons to defend itself against Pak 6) hatred: In a poll conducted recently it showed over 80% of Pakistanis view the US as an enemy. And the taliban as friends. The Pakistani military is also not a big fan of the US, and has been known to overthrow the govt from time to time, infact 1/2 of Pakistans entire existence has been under military dictators which came to power after a coup.
Its only the govt in Pakistan which regards the US as allies, so we cant push them too hard 7) Nuclear state( and perhaps THE reason) : Pakistan is a nuclear state which has a history of proliferation of nuclear technology. They tried illegally to sell their nuclear technology to libya and NK. If Pakistan goes bankrupt (which it is always close to) the first thing its gonna do is sell its nuclear technology or worst still nuclear weapons to other rouge states or terrorist organizations .
So just to prevent Armageddon, the us HAS to support Pakistans economy.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
