ECM Systems

What use would the ECM systems and/or other defensive systems on board a Tu-95 or Tu-160 be against an incoming AIM-120B/C launched from an F-15, F-16,F-22, Typhoon or Tornado F3. Does the launch aircraft have any influence with regard to the success of the missile against a target like a Tu-95 or Tu-160?
