It is an old saying but very rightly fits, whenever there is a fight for power. In Pakistan specially, where the all mighty FOUJ only understands one language and that is POWER, if you do not challenge them and show them the muscle, you are only gonna get bogged down and they will make an example out of you. FOUJ has always one or two under its sleeve and then use them as front faces, they used PTI against Noon, but Noon was experienced, they attacked them always, directly or indirectly, even whenever they attacked PTI, they always made sure to say loud and clear that it is FOUJ responsible for the failed selected government and they should share the responsibility. Noon and its leadership got reliefs everywhere, in courts, in cases, even in judgements where they were punished etc etc. Same is the case with Fazlu, who was only once asked to come to NAB and he started showing his muscle, directly opposing the FOUJ and telling them he and his militia will fix them that they will forget TTP.
In contrast, to all the above, PTI had a golden chance, I mentioned it on 11th April onwards, nearly everyday till 25th May march that this chance will never come back, the momentum will be lost, people will lose interest, will get disappointed, the FOUJ and its selected govt will stable their positions etc etc, if PTI does not make the timely decision to keep itself relevant. Again, PTI, do not know why, got scared, pissed in their pants and is now on a decline. Now damn if they say anything and damn if they do not. In both cases, they are now the target and seems like FOUJ has achieved its goal.
