They sure look like a pain in the wazoo
SL is a problem, no doubt
India is strung by domestic political compulsions in dealing with Sri Lanka in an meaningful manner unless things heat up badly.China & Pakistan have no such compulsions & both have stepped on the plate to support the SL.Government,which frankly uses excessive force.The Chinese are bidding to upgrade naval facilities in S.L.So the situation in S.L is a problem in more ways than one.
