Chikat, please take a look at the following video. It shows a couple of Tibetans scaling the Chinese consulate in Toronto and replacing the Chinese flag with the Tibetan.They were clearly breaking the law there.So please do not just blame the Tibetans in Nepal for doing so(although I still think that they were not breaking any laws at all).

And Berk, was Madhes ever an independent state? I do not think so as far as I know.While Tibet had been an independent state for centuries. So it's pointless to make this comparison.

Also can you elaborate on "Panchasheel".I'm sorry I've never come across this before.
