pashtun and afghan are synonymous. it is the title of pashtuns, no hazara, tajik or uzbek can claim this title infront of pashtun. with renaming NWFP to afghania ,we can regain our title of 'afghan'.
Thats exactly the mentality that hurled Afghanistan into civil war. The Tajiks, Hazaras and Uzbeks resent you claiming their country as solely belonging to you.
And obviously, these non Pashtuns arent threatened by you as they have fought you guys tooth and nail.
My Uzbek friend fought for the Northern Alliance, and I can tell you, he has no love lost for Pashtuns.
