That International Cricket Teams (Except Zimbabwe) have abandoned Playing Cricket in Pakistan - Obviously due to Security concerns fearing Taliban, ISIS & other Extremist outfits.
Also due to Match Fixing & Ball Tampering (Also Rampantly seen in India).
If Indians start Doctoring Spinning Pitches consistently - We can also foresee Foreign Teams Refusing to Tour India due to Adverse Playing conditions & undue Home advantage for Team India in the near future.
