Today, we find Muslim countries making military alliances with the kuffar and fighting alongside them. Turkey is a member of NATO and has sent troops to Afghanistan under the UN International Security Assistance Force. Pakistan has entered a military alliance with America to fight Muslims in the tribal areas and support the Afghan war. Many Muslim countries participate in numerous other military alliances and collective security agreements. Historically, the Khilafah entered in to military alliances with kafir states at certain times. In America and Europe we find a small minority of Muslims joining the western armies and being sent to Iraq and Afghanistan with some scholars even issuing fatwas that this is permissible in Islam. The Islamic ruling on military alliances and their permissibility is given below. This is taken from the book Shakhsiya Islamiyya (Islamic Personality) Volume 2 by Sheikh Taquideen an-Nabhani. The extract below is based on a draft translation from Ar
"Thoughts are the greatest wealth of any nation."
