Come on now. Do people bring strangers home at first meeting? No. Then why allow people without credentials into a compound? This was going to happen. This is a really bad practice. Informants don't happen, they are 'proven' to be invaluable. This is not a good methodology. At all.
And I am going to add this. If this is the level of 'infiltration' that occurs in Afghanistan, there is no excuse for the conflict there. This is primitive and can easily be overcome by Western application of policy. This is going to be over before it starts. NATO and the USA have to do some good assessments to the degree of force that is necessary in Afghanistan in their counter-insurgency methods. This is really primitive in its application. Letting down 'the coalition's guard' to enhance 'friendliness' is not a reasonable methodology. It will be exploited. The Afghan people have to come to realize this 'degree of anger' within their populous is a problem they have to overcome to increase their quality of life. NATO and the USA have a right to their sovereign authority within Afghanistan given the degree of corruption and the danger this country has become to the global community. The people of Afghanistan OWN THE PROBLEM, other nation's do not.
Corruption this deep within a society and its government will 'WHINE' about EVERYTHING in order to demoralize the 'controlling' entity/force. Making 'the connection' with the Afghan people is important, but, it should not be deadly. The Taliban are 'gaming' NATO. They are an enemy to the global community, they fall under the Geneva Conventions and we have a right to kill them. Ahhh, too bad.
These CIA agents were brought to Afghanistan in 'good will' to harness the ability of the Afghan people to generate an economy, secure their sovereign authority to be a nation. The agents felt so strongly about 'out reach' to the people they welcomed anyone that was attempting to be 'out of the control of the Taliban' to their compound to facilitate assistance. In turn, the Taliban attacked the very people that were there to help. These folks were civilians. The Afghan people and Karzai scream bloody murder then their civilians are killed, so it is our turn now.
We have a right to national security in the USA and Europe. We have a right to have the largest drug culture end. We have a right to stop corruption of a nation that has proven to support terrorist networks that have attacked the USA and allies. It's over. Afghanistan is going to correct its path or the global community will correct it for them. If that means there are mountains without recognizable borders to a country then that is what that means. If Afghanistan becomes an extension of its neighbor's sovereign authority to facilitate the end of deaths in bordering countries than so be it. I strongly suggest every country surrounding Afghanistan begin to plan to extend their sovereign borders to absorb this dangerous entity in the region.
The surrounding nations to Afghanistan might want to begin a summit process to coordinate their intentions and prevent conflict between them. They need to recognize human rights issues regarding cultural genocide and the right of the people of Afghanistan to continue their ethnic cultures regardless of the control of any sovereign authority that annexes a portion of the region. I am dead serious.
