Robert bhaijan. You seem to be correct. Sharif brothers seem to realize where their future lies. The piece below from the Dawn makes interesting reading.
DAWN - Opinion; February 18, 2009
In this context and coming as it does after a long period of mutual acrimony, Monday’s meeting between Punjab chief minister Shahbaz Sharif and Sindh governor Dr Ishratul Ibad should be seen as further proof of the fickleness of politics. Until recently, Mr Sharif’s party saw the MQM as its worst enemy. In fact, the bloody incidents of May 12, 2007 had led the Sharif brothers, their party men and allies to set in stone their aversion to the MQM at a London meeting. That the PML-N has apparently swallowed its abhorrence for the MQM can be interpreted in only one way: the Sharifs are realising that they cannot go further than their citadel in and around Lahore by antagonising everyone who is anyone in the rest of the country.
