Let me write again so you can read slowly over and over:
- US attack Afghanistan, Taliban run to Pakistan, US blames Pakistan
- Pakistan attack Taliban they run to Afghanistan, US blames Pakistan
- Something happens in Afghanistan, US blames Pakistan
- US attacks Taliban in Afghanistan, they run to Pakistan, US blames Pakistan
That is because desperate people do desperate things... To mask their 7 year long failures in Afghanistan they have to blame Pak and put it on the spot.
Success has many fathers failure is an orphan.
