Win over, establishment

Washington, Jan 25 (PTI) Suspicious of deepening ties between India and the United States, Pakistan is reluctant to plunge into war with Afghan militants and even high-profile visits of US officials have failed to win over a military and civilian establishment in Islamabad, a media report said.


The recent visit of US Defence Secretary Robert Gates and US Special Representative for Pakistan and Afghanistan Richard Holbrooke could not convince Pakistan to go ahead full throat in its war against terrorism.
"One major obstacle, analysts said, is the close relationship between the United States and India," The Washington Post today reported in its dispatch from Islamabad.
"India-Pakistan relations are mired in mistrust, with India suspecting Pakistan of colluding in a terrorist attack in Mumbai in late 2008, and Pakistan suspecting that India uses Afghanistan to launch anti-Pakistan subversion," it said.

Could you please explain to me what the emboldened parts mean?

I guess "win over" means "win against", but no idea what "establishment" means here.
