problem is
it is funded and supported by your most important and powerful ally the Saudis. also it provides the muscle to the current ruling party (another beneficiary of saudi royals) that is using its leadership to settle their joint personal scores against former army chief. the Red mosque leadership has filed a murder case against the COAS.
back in 2007 our military did raid the place but the public reaction was played against us and we failed to sell it to public. the administrator despite its aggression and killing (of an army ranger) before the raid , came out as the victim and the entire atmosphere was used by the political opponents against the then government of Musharraf who headed the army as well.
its like someone files a murder case against Mrs Teacher on the killings by SAS in the Iranian embassy siege. this is how the ludicrous shit happens in Pakistan. the former president is facing treason charges for announcing emergency back during his rule (something similar to what was announced by the French PM after the terrorism) and he also faces murder charges for the killing of two terrorist leaders one the brother of current red mosque cleric who took up arms against the state and the second for the killing of a Baloch chieftain who took up arms against the state and led an insurgency including the blowing up of infrastructure and killing and abduction of foreigners and non baloch people.
so in short there is no chance of any raid on this place. our media back then sucked the taliban cock so hard that it played them as victims and deionised the Pak military to an extent that people spat when they mentioned our forces . this was the time when we had joined the WoT. and were cursed and mocked by islamist parties including current ruling party for becoming hired guns of Americans and killing fellow dear muslims.
in short we sucked *** so bad that despite our contributions, sacrifices we were mocked, hated, cheated , betrayed and blamed by friends, allies and foes alike. and we got only ourselves to blame.. very lame and pathetic representation and media presentation by our military. this same place went on American media headlines when the female assassin from California was linked back to this same place but still no harm done to it. encouraged by the presumed invincibility and lame duck reaction by the state, the red mosque administration is once again taunting the state and staging aggressive marches and openly supports and invites Daesh leadership. but since you guys cant say a word against Saudis and since this guy gets direct funding from saudis just like all other wahabi terror proxies so he remains invincible
there you go, thats explanation enough for ya?
