It is very correct, that nation can be not base only on one ethnic, nation include all ethnic. The examples of this writer are connected to intrigues and they are rubbish, first of all it is not true and fully false, that the USA citizen both with white skins one as seller and an other one as costumer will not ask each other, because they are both white, therefore they will talk about decreasing of price, but the behavior of two black people is opposite, they are feeling themselves to each other closer, therefore the costumer is getting decrease of price( it is ridiculous, primitive falsehood and shameful). The same mechanism is used in Afghanistan, two Dari speaker one staff of office and an other one client will not discuss about obliging, the staff will do his job base on existed rule, but among two pashtunen will be not keep the rule. How can you circulate such horrible falsehood? First of all, the prices in USA are labeled every where, I do not know, are you talking about Kabul USA?, there does not exist negotiate at all, secondly among two pashtunen never exist such style of cooperation, for example, Amin, Taraki killed opposite to Karmal most pashtunen, in fact all khalqi eliminated mostly pashtun and destroyed the pashtun areas, Gulbudin killed opposite to Rabani in all pashtun villages many farmer, this why he can not go to Paktia, Paktika and Khost area, Saiaf killed lot of Hazara on instruction of north alliance, gulabzoi and aoalumi both of them killer, they are sitting with Rabani on one Table under logo “Alliance of nation”, but he is hated by pashtunen, because they are killer and killer are coming with killer together, if we see the present situations, Karzai, Ahadi, Pashtun, Atmar, Arsala and other are Pashtunen, they are installed by America like the communist by former UdSSR, by their ruling getting bombs Pashtunen, destroying their areas and the north Alliance advise them for more killing and destroying in additional, if you want to start your intrigues, then please try to bring realistic examples and not use rubbish none senses, these reflect more your low level character as you have it
