|Not only does the US drone murder Pakistani civilians, it also "accidentally" bombs Pakistani military check-points.|
The United States has always preferred Dictators ruling Muslim nations. The Shah in Iran, Mubarak and the Generals in Egypt, Suharto in Indonesia, Saddam Hussein in Iraq, and General Zia in Pakistan. They provide "stability". If they step out of line the US can always label them Hitlers, bomb and invade their nations under the guise of humanitarian liberation and maintaining "regional stability". It's advantageous to have well armed despots beholden to the largesse of the Pentagon.
US/NATO policy suppresses democracy in Muslim nations. The United States, UK, and France have all recently announced major military sales to Middle Eastern despots intent on strengthening counter-revolution. Arms sales to states busy crushing peaceful protests does not support the "Arab Spring"(I hate this fucking term. Revolts against US backed despots who have allied themselves with the US in the "War on Terror" are not a sudden awakening. They are not as puerile as a fucking advertising slogan for a Bar of Soap.)
US military and intelligence operations inside Pakistan have exacerbated civilian mistrust of the government. The Government allows US free reign to drone murder hundreds of civilians with impunity. When the United States kills military personnel it enrages them further. They rightly view the so called legitimate government a spineless client state taking orders from Washington, D.C..
All of this uncovers the true aim behind destabilizing Pakistan. The United States wants a military dictatorship in Pakistan. If drone murdering civilians can't bring it to pass, then maybe some soldiers will have to be "accidentally" killed. "Stability" is "worth it" to the US. They weren't above mass murdering nearly a million Iraqis for it.
