You think one country can just invade a disputed land, claim it and expect its opponent to accept the invasion and let it go? The world is a different place now where empires don't collapse.
This is the first time I'm hearing of Operation Gibraltar. How convenient of our Pak Studies (read Lie Studies) syllabus to have left it out completely. And we were told India attacked us first! :hah:
You can't instil true patriotism in a child by feeding him lies and half truths.
No, world was indeed a different place 48 years back.
No army has ever held onto a territory without supplies and supply lines. So with no land route ava. to Kashmir India could have rendered toothless. Just like we still hold the area captured in 1948 war. and similarly what we lost in 1971 we can't regain.
Secondly no country has held onto a colony for ever
I least expected of you as the person who didn't knew of Operation Gibraltar.
