The security situation of Afghanistan in year 2015 had been proved more deteriorated and disastrous as compared to the previous years - since 2001. An attempt has been made to evaluate the Taliban's spring offensive and the capability of the Afghan National Defense Security Forces (ANDSF). At the end of 2014, most of the foreign troops withdrew from Afghanistan and transferred the responsibility of security to the ANDSF. The ISAF and NATO forces believed that the ANDSF were then capable to uphold the security situation inside the country - that was being trained by them. Besides analyzing this security situation of Afghanistan in year 2015 the study also examines the developments regarding President Ashraf Ghani's policy towards Taliban as well as peace process which all gone in vain due to some complexities.
