PTM is the political arm of the TTP.

You can use them to counter the TTP threat because they are the reason it's expanding & reaching more Pashtuns. 

Both TTP & PTM used the War on Terror to launch themselves. 

One used weapons & violence. 
The other used the violence to radicalize Pashtuns against the armed forces. 

Remember it was PTM who coined the chant "Behind this uniform is terrorism," while TTP branded the Pakistan Army as a "Punjabi Army" only interested in killing Pashtuns.

Sadly, neither bothered to see the number of innocent Pashtuns, police officers, soldiers, and officers embraced martyrdom due to these groups behavior.
