I can say that by common sense.
Common sense doesn't apply here-- its world politics- battles for resources-- power, here its not so common as you think.
The US initially came to Afghanistan primarily with a sense of revenge (the tax payers wanted their revenge) under the garb of "War on Terror". They have achieved it, kicked the Talibani arse and can now move away (the tax payers now want this) leaving Afghanistan and Pakistan to sort this mess out for themselves.
Its easier said than done, if thats so much simple, whats stopping US from getting out of Afghanistan, isn't thats precisely what majority of Pakistanis and Americans want?
If it was just for revenge the revenge was taken on very first year of the War, when they defeated the Taliban, but No they had to go for Iraq-- This region is strategically too important for US to leave just because the tax payers wants it.
And you are just exaggerating the threat - nothing whatsoever will happen to the US mainland. They are not Pakistan or for that matter India to be lax and allow bomb blasts happen all over the place. They have awesome network of Electronic and Humint and more importantly the god-given isolation of the land.
Exactly opposite had happened on 9/11 on 7/7 or 26/11 for that matter,
The Super Power got taste of its own medicine, The city of cameras got the taste of too much confidence, and a country of excuses got another excuse to feed on. You are over simplifying the situation and the mess it will create or had created.
The primary reason US is there in Afg is to rebuild Afghanistan and make them a stable country.
What was the reason again?-- Just Revenge--Rebuild-- or No interest at all, i do not understand this each post of your gives different reasons--
Say none or All.
Did you mistake what I said as US capturing your nukes ?? NO.
I did not mean it --- I meant the threat implied by you in the previous post -Pak failing and consequently nukes falling into wrong hands.
That is just a bluff and not long before US calls it.
We have always maintained that the Nukes are never going to fall into wrong hands-- and when i said no one wants a nuclear armed country to destabilize-- i didn't meant what you get--
Pakistan is never going to Fail, we still have more friends than enemies.
