When you're engaged in an absurd "war on terror" (or whatever it is now called by the Obama administration) you're going to get into the sort of "diplomatic imbroglios" that is currently happening with Pakistan and the U.S.
Some background is in order.
Pakistan has been a reluctant "partner" in the war on terror ever since Bush invaded neighboring Afghanistan in 2001 in retaliation for the 9/11 attacks.
As a recipient of billions in U.S. military aid, Pakistan was obliged and became the main supply route for the necessary supplies required for the U.S.to conduct its war in landlocked Afghanistan.
The border between the two countries, primarily the Pashtun areas, is hardly recognized by the indigenous population in either country, but is the area that spawned the Taliban which governed Afghanistan and was allied with Pakistan until it was overthrown by the U.S. invasion.
With the overthrow, Taliban leader Mullah Omar escaped along with his other Taliban henchmen and dispersed into neighboring Pakistan, primarily into the Pashtun populated Federally Administered Tribal Areas.
It is through such Pakistani Pashtun populated areas that the majority of U.S. supplies must traverse into Afghanistan. From the beginning of the Afghan war, this route was notorious for corruption and the payments of bribes to the local warlords BEFORE the truckloads of supplies were allowed to pass and which the U.S. secretly paid, (much of which ended up in the hands of the Taliban, which not so ironically the U.S. was also fighting. But that's a whole other story.)
So this sordid business went on for years without much notoriety.
That is until the U.S. and the new Obama administration got enamored with and escalated drone strikes and missile attacks launched against purported "terrorists" hiding out in neighboring Pakistan, which (unintentionally, according to U.S. accounts) killed innocents which inflamed the Pakistani population.
Other incidents occurred within Pakistan such as CIA agent Raymond Davis, disguised as a diplomat, yet carrying a pistol, gunned down two Pakistani men on a motor scooter in La Hore, Pakistan for which he was initially held and charged for murder by Pakistani authorities, then subsequently released in lieu of paying restitution to the victims families, (which needless to say, didn't sit well with the Pakistani people and spawned widespread protests).
