Pakistan has made too many enemies lately, troops and resources are now being used to defend both its eastern and western borders simultaneously.
Maulana Abul kalam Azad very logically said that Pakistan would make enemies of almost all of its neighbours.
The relation with Indian was always bad, relation with Afghanistan was Luke warm to brotherly now turned to extreme hatred, relation with Iran is not very friendly as per recent checkpost attacks and terror attacks. The only country that has good relations with Pakistan is China, now when will it turn sour ( mostly because of terrorism) is anybody's guess.
Now with the new threat of ISIS in south asia, things will get tough for all countries.
