Coming to REAL islam, the true original teachings of Rasulullah (saw) and accepting the Mahdi (as) who has come is the only answer to the problems in the muslim world...
the reason afghanistan is suffering in my opinion is because of this, which you can read here (close to the bottom):
There also came to Qadian, in 1902, a noble and saintly scholar from the Royal Palace of the King of Afghanistan. The saintly person was Sahibzada Abdul Latif of Khost, Afghanistan. He was himself a renowned scholar, acknowledged as the most eminent divine in Afghanistan, with a huge following of his own. He was held in great esteem even by the King who had appointed him as the Court Scholar. Sahibzada Abdul Latif did not lack in material wealth. His estate spread over a hundred thousand acres in the province of Khost as well as another considerable estate in Bannu, on the frontier land.
In 1893 he was appointed a member of the Royal Commission, set up to negotiate terms with the British and the two parties camped near the border in Parachanar. Among the English group was a stenographer, from Peshawar, who was a follower of the Promised Messiah (as). He was Chun Baadshah who, seeing in Sahibzada Sahib a saintly and scholarly person, courageously presented him with the Promised Messiah's book, A'ina Kamalat-e-Islam. The Sahibzada Sahib spent the whole night captivated by that book and by the morning he was convinced that the person prophesied by the Holy Prophet (as) of Islam, as the Messiah and Mahdi was doubtless the writer of this book.
One of his closest disciples, Sayyed Abdus Sattar Sahib has related that Sahibzada Sahib read this book before them and declared that this is that Mahdi who was to come. The rest is history! It is the story of perception and acknowledgement of truth, of the strength of love of Sahibzada Abdul Latif (ra) Sahib for his beloved Master, the Promised Messiah and Mahdi--a love for which he paid with his life. He was, however, not the first martyr among the followers of the Promised Messiah (as).
Before visiting Qadian himself, Sahibzada Abdul Latif Sahib sent one of his trusted disciples, Maulvi Abdur Rahman to Qadian to observe the Promised Messiah (as) and his activities and to send back a diary of his observations. Upon his return journeys to Kabul, he brought for his Master various books of the Promised Messiah. In 1901, on one such return journey from Qadian to Afghanistan, he had with him some literature of the Promised Messiah (as) including his pronouncements upon the issue of Jihad. This was reported to the King who issued orders for his arrest and he was subsequently murdered in jail by being suffocated with a cloth. He thus became the first martyr among the followers of the Promised Messiah (as).
Records do not, however, show that Sahibzada Sahib was interrogated as a result of this incident and he continued to send other close and trusted disciples to Qadian with the same mission. Finally, in 1902 he decided to meet the Promised Messiah in person. When he arrived in Qadian and saw the illuminated and holy face of the Promised Messiah (as), it was a case of love at first sight. He had no hesitation whatsoever in accepting Hadhrat Mirza Ghulam Ahmad (as) as the Promised Messiah and took the Oath of Allegiance at his hand. He stayed in the company of the Promised Messiah (as) for several months and parted from him very unwillingly.
Upon his return to Afghanistan, he was asked by the King and the clergy to renounce his acceptance of the Promised Messiah (as). He refused to reject the claims of Hadhrat Mirza Ghulam Ahmad to be the Promised Messiah and Mahdi, and as a result the King of Afghanistan, in connivance with the Court clerics, ordered his imprisonment, pending execution. On 14 July 1903 the King ordered that his already shackled body should be dragged along the streets of Kabul, by a rope pierced through his nose--dragged thus to the place of his execution. People in their multitudes lined the streets, jeering and mocking. At the place of his execution, he was half buried in the ground and the first stone was hurled by the chief Qadi (Judge) followed by the King himself, and then by a hail of stones--(O human cruelty! Do you know no bounds?) His body, buried under the heap of stones, was later given a secret burial by his disciples. Thus ended the saintly life of Sahibzada Abdul Latif Sahibzada, martyred in the path of love, in the path of God, faithful to the end.24
Commenting on this episode, the Promised Messiah (as) wrote: 'Prior to this tragedy there had also occurred the murder of Mian Abdul Rahman, one of my followers, on which God kept quiet, but He will not overlook this brutality and the terrible consequences of this event shall be witnessed. It has been reported that after the killing of the deceased martyr by thousands of stones, an epidemic of cholera broke out in Kabul and a great number of people, including prominent men and dignitaries of the state and a number of the Amir's relatives, perished. But that is not all. This was a most merciless murder which has no parallel under heaven. Alas, what a pity! What has this ignorant Amir done? He has brutally killed such an incomparable, innocent and righteous man and has ensured his own ruin.
O land of Kabul! You are a witness to the heinous crime committed on your soil. O miserable land! You have, in the sight of Allah, been condemned as you are the scene of this most atrocious crime.'
