Exactly. This is the question that any guy with a functional brain would ask. Except two kind of creatures.

Exactly. Just after the incident he talked to media and blamed Pakistan there and then. So if he knew from beginning this was going to happen,how come he didnt stop it? Its a same tactic of our neighbor's he and almost whole Afghan Govt use to blame Pakistan for their incompetence.
Here is sort of same analysis by BBC too:
"
Who were the Kandahar attackers? Dawood Azami, BBC World Service, Kabul
There are many theories as to who was behind the guesthouse attack, but three are seen as being most likely:
The first is that the Taliban or their allies in the Haqqani militant network carried out the attack. Kandahar police chief Abdul Raziq, who was present when the blasts took place, has been on the militants' hit list and is known to be staunchly anti-Pakistan. The Taliban denied involvement but may have done this when they realised the victims were UAE officials.
The Taliban are on good terms with the UAE and usually avoid attacking diplomats from countries not involved in military operations in Afghanistan.
Regional tensions mean intelligence agencies from other countries could be involved. Pakistan and India have long tried to shape events in Afghanistan and recently Gulf Arabs, led by Saudi Arabia, intensified their efforts to increase their influence. Iran is not happy about this and has established what it calls "contacts" with the Taliban.
The third possibility is that of local rivalries between officials and politicians in Kandahar. They have sometimes been accused of using the Taliban to harm each other. The Afghan government has launched an investigation to identify those who carried out the attack and their motives."

Looking at the current scenario only 3rd theory comes up strong as along with Talis both Pakistan and India will never carry out such an act which can harm relations with UAE. And m sure that Gen (Retd) Pasha would have already shaped up things back in UAE.
