I agree there could be more done but whatever they have done so far is much better than so called Indian Muslims.
After 1984 massacre they pickup the arms ,the khalistan movement was infact born because of that and they did get a training and funding from a regional power . So please do some research before you talk.
Ok, how many assassinations have they successfully carried out of their supposed enemies? How many Indian security forces or politicians supposedly denying them their independent state have they killed? How many of them have been martyred doing so?
Tamils, naxals, Islamic State, lone wolf islamists and tribalists have done more for their causes than 30 years of supposed Sikh agitation.
Seriously, India's Sikhs are good for Bollywood or charging suicidally head first up Tiger Hill and and that's about it. All the bravado about khalistan is fake. Delhi doesn't fear Indian sikhs in the slightest.
1984 happened. It would have spurred a civil war for most peoples but Indian Sikhs surrendered to the hindutva mobs. In fact, that was India's big chance to erase hindutva as a mentality - both the overt fundamentalism among RSS and the hidden extremists who posed as moderate Congress (there are plenty of them by the way - genuine secularists in india have been in steady decline). Sikhs could have initiated a revolution but failed.
It's up to the Muslims I'm afraid.
Edit: as per wiki, I stand corrected. The mighty khalistani nation did actually achieve something after the Indira assassination. After Indira Ghandi, there were further "militant attacks" in 1985.
And then I presume India granted them independence, justice and full recognition of the genocide that took place in 1984.
Or maybe it's just the state of Ontario who decided to recognise all that stuff.
