India can show as such but never can be regional police as desired by Delhi. Lastly, India was sending troops into Afghanistan too but back tracked knowing the outcome for having such an opposition that may deal it more strategically as well as well trained. India chooses interfering points very wisely especially where the destination is not strong enough and since a good lesson in Sri Lanka never attempted as such. Looking at the same habit of India, one can see as the reason behind all Indian internal movements where moists, nagaland or Khalistanis along with many more calling upon separation.
There is a lesson as do not interfere into others internal matters and live in peace but once India cross the line, cannot ignore the back fire that other parties may exploit its weaknesses. Such kind of games are not one sided but always played with gain & loss principle. India starts interfering into other regional matters, automatically allowing others to take advantage. As said, don't act police as such does not matters at all even after all those big talks.
