What issue is facing nato nations at the present time?

The issue that NATO is facing is the rebuilding of Afghanistan devastated by the war against the US.

Explanation:

NATO is an intergovernmental military alliance created after the end of World War II in the context of the bipolarity formed between the United States and the Union of Soviet Socialist Republics during the Cold War period.

Since January 2006, NATO's International Security Assistance Force (ISAF) has begun replacing US troops in southern Afghanistan with Operation Enduring Freedom. The 16th British Air Assault Brigade (later reinforced by the Royal Marines) formed the core of the southern force of Afghanistan, with troops and helicopters from Australia, Canada and the Netherlands. The initial force consisted of about 3,300 Britons, 2,300 Canadians, 1,400 Dutch, 280 Danes, 300 Australians and 150 Estonians. Air support was provided by American, British, Dutch, Norwegian and French airplanes and helicopters.

In January 2006, NATO's goal in southern Afghanistan was to form the British-led Provincial Reconstruction Team in Helmand, while the Netherlands and Canada would direct those projects, respectively, in Oruzgan and Candaar. The local Taliban have expressed opposition to the arrival of the new force in power promised to resist.
