In this late April 1988, file photo, Soviet soldiers observe the highlands, while fighting Islamic guerrillas at an undisclosed location in Afghanistan. Moscow and Washington are intertwined in a complex and bloody history in Afghanistan, with both suffering thousands of dead and wounded in conflicts lasting for years. Now both superpowers are linked again over Afghanistan, with intelligence reports indicating Russia secretly offered bounties to the Taliban to kill American troops there. But analysts suggest that the two adversaries actually have more in common, especially when it comes to what they want to see in a postwar Afghanistan: a stable country that does not serve as a base for extremists to export terrorism. Both countries also are aligned in their opposition to militants from the Islamic State group. (Photo by Alexander Sekretarev/AP Photo/File)
