The way Zardari is sucessfully working, you think he is gonna let Sind slip from his hands!!How can the other half be lost? It will always be there.
He will create a separate country than let it go. Remember "Pakistan Khappe".
He gave the signal, that if he wanted to he could have said "Pakistan na khappe".
He will say "Pakistan na khappe" whenever he sees the chance to rule over Sind.
