Gentelmen i m sorry for being involved in to your topic.i know this is something should be discussed between you brothers from pakistan.but let me add my thoughts.
As a Turkish;my country is a republic.but till 1928,there was a hint on the religion of the goverment.but this hint was removed in 10 april 1928.so our country became a secular country.
if we ask why it was done;our country had a ''nation building phase''.Turkey was founded as a muslim country,but later it was named as a secular-nation state.the positive sides and negative sides of this matter can be discussed later.let me get back to our topic about Pakistan.
Pakistan was founded as an Islamic republic.An islamic republic because the referance point of the republic is Islam.
lets have a look at the ethic form of the pakistan;
% 60 Pencabi (i hope i write correct.please correct me if i m wrong brothers...)
% 11 Sind
% 10 Pestun
% 8 Urdu
% 8 Jat
% 2.5 Beluci
% 1 others
Brothers;all these ethic groups are Muslim.if we remove the Islam tag from the name of the country,what will be the main idea to hold all these groups together?How will these groups stick together?also it is too late for Pakistan to start building a nation state like Turkey and other European countries.
as a Turkish,i can say that we have some problems because of the misapplication of the secularism and nation state.(but i hope all these problems will be solved very soon.)
for this reason,the removal of Islam from the state tag ;may cause many problems.Our beloved founding father Muhammed Ikbal's way is the correct way.another option may cause a civil war in Pakistan.
so,lets keep saying: Pakistan, ke matlâb ya? Lâ ilâhe illAllah
My Greetings
