Pak has slammed krishna. Now what did krishna do. Well he did what he thought his job is. That is making the statement. He in his interview to headlines today said "India has been appreciated for its tolerance and statesmanship in the aftermath of the 26/11 strikes. But any repeat of such attacks will have serious repercussions on bilateral ties. Let there be no mistake about this."
"We want cordial relations with Pakistan but such statements raise questions about the motives of the Pakistani government,"
Now the line in bold is what pakistan seems to have found immature!!!!!!!!!!. How can India want cordial relations with pakistan. Atleast for another 10-20 years , pakistan's domestic politics would run on anti-India , anti-usa and anti-Israel!!!!!!!!!!. So its immature from part of krishna to have said cordial relations thing. For rest part of statement pakistan seems ok.
