Moscow also supports Hezbollah against Israel and is the primary ally of the Iranian government the White House consistently condemns for sponsoring international terrorism. Moscow is not a reliable partner for Washington in combating international terrorism. Any agreements with Russia against IS have limited value. On the contrary, it would encourage Moscow to intensify its sponsorship of terrorism against Western interests in the calculation that this will bring further concessions from the White House. In Afghanistan, Russia provides military assistance to the Taliban against the central government supported by Washington. It provided weapons to several terrorist groups, including Hezbollah, helped devise aircraft hijackings during the s, and promoted the concept of suicide bombings against both military and civilian targets.
