As per recent reports, it has been unveiled that the US and Afghan officials have been coming up with conflicting reports on compromise for a future security deal.

The Afghan officials have stated that the US has proposed to give a letter, which will be inclusive of all the mistakes that have been committed by America in the past. But the report has been denied by US National Security Adviser Susan Rice.

He was of the view that nothing of such sort has ever been said. Experts were of the view that the US is having concerns with regard to Afghan negotiation steps.

It is henceforth, being considered that deal could get cancelled as the US would not be able to accept the terms proposed by Afghan.

It has been found that Afghanistan wants that letter in return to allow US troops to be in the country. But if the deal is not finalized then the US would be left with no other option but to withdraw its forces from Afghanistan.

President Hamid Karzai's spokesman has affirmed that US Secretary of State John Kerry has offered to send the letter. But Rice has affirmed, "There is no need for the United States to apologise to Afghanistan - quite the contrary".
