Irrespective of the fact that these posters were displayed by the establishment lovers or the PML-N government, the military has been ridiculed either way.
Had the military restricted itself to defence duties and not gotten involved in politics, they would not have been ridiculed like this. Ever since the dharna, PML-N social media teams continuously humiliate the military. No matter how objectionable or unpatriotic it may seem, the military establishment has brought this ridicule upon themselves through their own deeds.
The establishment can control the print and electronic media but they can never ever control the internet. They will continue to see more humiliation till they mend their ways.
