The horror of the 9/11 attacks had a huge impact on international relations.
People around the world had been affected by the attacks and horrified by the actions of those involved in acts of terrorism.
As a result, international relations changed to fight against a new ‘unseen’ enemy.
Countries around the world gave their support to the USA and believed that a united front was essential if this new type of enemy was to be destroyed.
This coalition of countries promised to help the USA hunt for Osama bin Laden and Al-Qaeda.
While the initial offensives in Afghanistan were successful, coalition forces had to move from attacking the Taliban to rebuilding Afghanistan.
While the Taliban was virtually destroyed, Al-Qaeda still held on in parts of the country.
The Taliban was not out of business and took advantage of safe havens in the mountainous areas along the Afghanistan-Pakistan border.
Realising that Afghanistan needed more help to create a stable government, the International Security Assistance Force was created in 2003 by the UN to help rebuild Afghanistan.
Despite this, in 2003, a rebellion to bring down the new Afghan government began against the American and NATO forces.
Attacks continued on and off for several years, with many Afghan civilians being caught in-between, some ultimately losing their lives.
During all this, a new, democratic government was established in Afghanistan.
