No, that isn't what is going to happen. The support WILL be qualified; the Chinese will not permit Pakistan to pull its tail.
America showed great patience before and competence during the Abbottabad raid. The competence everyone knows about. The patience part people don't: for over twelve years and three U.S. presidents and multiple Pakistani leaders Pakistan had promised to deliver bin Laden. That's right, even when Bill Clinton was president and OBL was in Afghanistan. Pakistan promised but did nothing and eventually even disbanded the P.A. unit dedicated to looking for bin Laden. No surprise, then, that when U.S. officials strongly suspected - with some evidence - that bin Laden was comfortably ensconced in the bosom of the Pakistani military that they concluded Pakistan had either been lying to them or continued to boast, "No Osama here!" to cover up their own ignorance.
I don't doubt that traveling Pakistani officials are greeted with smiles in Moscow and Beijing . A smile is what's left when people try to restrain their mirth and relief. Didn't the Abbottabad episode demonstrate that a devious Pakistan is not to be feared nor (as the U.S. demonstrated) respected? After a while they may tire of the amusement and lose interest in their Pakistani guests entirely.
