I think it is clear that PTI can only make government in KPK. It will be a split mandate and in sha Allah PTI will not join any status-quo party for power.
Situation is not ideal but everything is not lost. The good thing will be that they can still show performance in KPK. They can:
a) Eliminate corruption in KPK
b) Raise strong voice against this war and drones by passing resolutions and active protests on the streets or even blocking supplies
c) Strength the system of justice in KPK
d) Conduct local bodies elections
e) Help promoting peace and local businesses to improve employment situation
f) Make it a good place to invest for private sector especially in hydel power, gem stones, engineering etc
g) Give incentives to the private sector to invest in research and development through universities
h) Give results in other key areas which are part of their manifesto
In National Assembly, they can make strong noise on policy issues related to local and international affairs.
