You go into Punjab and you will find many Sikhs who have twisted the sikh religion around - doesnt mean that all punjabi sikhs are bad. Therefore stop judging a whole sect of sikhs on a few people who have messed around with it.
Correct me if am wrong but Sikhs who want to join the US army must cut their scalp hair and beard so i think your definitly not going to inspire Keshdarhi sikhs to join the army but you may inspire others.
Why dont you start this seva of hardcore military training in Punjab - you sound very passionate about it and im sure you will get more than 35 000 sikhs to join - This is an ideal chance for you to back the talk with the walk.
Thats a decent start - irrespective of who you are fighting for atleast you will get to fight extremists - something the sikh faith has promoted , what about the saint aspect of a sikh saint soldier ???
