State is already doing that
1 i dont see any activity or response from Pakistani state or even communities
2nd bit which i find strange is every Pakistani you meet will say i will even die for my country but never actually see people standing up for its national image.
Why you dont see Pakistani consulates and PTI groups Supporting and sponsoring rallies against these idiots , neither against India.
How can you fight propaganda warfare without actually taking any precautions, State itself need to understand they will have sponsor Pro Pakistan Media outlets in western countries, Support people who Pakistani core beliefs and let them fight media war,
3rd I don't understand the Afghan Jacka** who are so aggressive towards the police and Pakistan if you are so macho why dont you go back and actually fight for your countrys own future. Atleast you will put up better fight then ANA did.
