Defence sources have said that both the US and British governments no longer expect any of Nato's main partner nations to send more troops to serve in southern Afghanistan where the Taliban insurgency is most fierce.
Despite high level lobbying by Gordon Brown, the Prime Minister, and senior diplomats no country has come forward to share more of the war fighting burden being felt by British and US troops in the south of the country.
Sources have also indicated that both Britain and America may have to commit extra forces to the campaign if Canada withdraws all of its 2,800 troops in the next 18 months from the troubled Kandahar Province.
Britain has continuously called upon its partners to commit more troops and resources to the war since the insurgency began to gain momentum in southern Afghanistan.
But the only country to make a significant response was France when it sent around 1,000 extra troops to Afghanistan last year.
The issue of Nato's approach to the Afghanistan crisis was highlighted by Eric Joyce MP, who last week quit his post as a junior aide to Bob Ainsworth, the defence secretary, when he called into question the alliance's commitment.
In a letter to the Prime Minister, he wrote: "For many, it seems that Britain fights; Germany pays, France calculates and Italy avoids. If the United States values each of these approaches equally, they will end up shouldering the burden by themselves."
General McChrystal, the commander of the International Security Assistance Force (ISAF) in Afghanistan, is also expected to raise the issue of Nato's commitment to Afghanistan in his review of the strategy of the war in Afghanistan.
Rather than calling for more troops however, he is expected to ask for Nato partners to volunteer more specialist "niche capabilities" such as surveillance, bomb disposal, helicopters, transport and surveillance aircraft.
But many officials in Whitehall remain convinced that Nato's response will be woeful.
Since 2001 the US, which has 29,950 troops in Afghanistan have suffered 813 deaths, while the Britain, with 9,000 troops in the country, has suffered 212 fatalities.
By comparison Canada, with 2,800 troops have lost 124; Germany with 4,050 have 33 dead; France with 3,160 has 28 dead and Denmark with 700 troops has lost 24.
Over the last year the nature of the war has changed significantly with the Taliban resorting to the use of improvised explosive devices to attack troops.
In July there were over 100 IED attacks in Afghanistan, the vast majority in the south, killing 459 soldiers, the majority of whom were British and American.
Britain has so far lost 75 soldiers this year in Afghanistan. The bloodiest months were July and August in which 41 troops died, of whom 34 were killed by IEDs.
One source said: "We have made repeated attempts to get Nato to shoulder more of the burden in Afghanistan but without any real success.
"There has been some tinkering around the edges but there is no real commitment from any of our partner nations to commit troops to an operation which at best has reached stalemate and at worst is being lost.
"There is now a sense of resignation over this issue. We approach Nato summits with little or no hope that anything will change."
Patrick Mercer, The Tory MP and former infantry commander, said: "Unless our partner nations start to pull their weight in terms of combat units then Nato is doomed.
"You can't have a handful of nations doing the fighting and dying and everybody else doing the computers and mobile bath units without confidence in the whole alliance being eroded."
Details of Britain's growing frustration with its Nato allies follows the disclosure that 16 Air Assault Brigade is set to be the first unit to complete three full tours of duty in Helmand when its returns to the country next year.
The Brigade which includes the second and third battalions of the Parachute Regiment, has lost more troops in Afghanistan than any other British unit.
British commanders are known to be concerned that so-called "Afghan fatigue" will have on manning within the Army.
The growing number of casualties – the last few months have been the bloodiest for the coalition in recent years – is known to be having an impact on the effectiveness of the Army and some senior officers now believe the size of the tasks of reconstructing Afghanistan while trying to contain the insurgency is a commitment beyond Nato's means.
