Both the SL airforce chief and Navy chief are alumnus of Pakistani Defence Academy .. SO which means Pakistan had good infiltration in the Sri Lankan establishemnt.
Pakistani Commandoes and Air Force Train SL Army.. Besides, Sri Lanka has a large and influential muslim population which are now believed to be ISI-Infiltrated..
Traditionally the pro-India elements have been the Tamils .. That is changing and very soon India will not have a solid foot in SL ..
