Problem is that Siachen should be
de-militarized and both Armies should go back to their positions of 1984 ....
Only advantage of Siachen was that Pakistan Army got a strategic advantage over India by capturing point 5353 during Kargil war ... (Even after the war was over and despite Indian Army's various effort to take back point 5353 , Pakistan Army still maintains that strategic height..and now it has 'matured' that point very well)...
Just a tid-bid .. Point 5353 is the
highest peak in that region and Pakistan Army's artillery can target your NH-1 from there ...
Other than that , Indians got NO strategic advantage from Siachen and end up giving a strategic advantage to Pakistan
