I just left Barcelona a couple hours ago, the capital of Catalonia. Everywhere you look, Catalan flags, signs demanding 'democracia', demanding freedom. I'm told this is just normal for the region, but if this is normal then independence is eventual.
Well, it is normal since independentists have controlled Catalunya since 40 years ago. It used to be that 20% of the population was independentist through, now is over 50%. For example, they choosed school principals among independentist so now over 85% of them are Catalan language teachers that tend to be independentist. This way kids could be directed to be independentist too. The same happened with the local media…
Catalonia would have trouble becoming genuinely independent without approval from Spain. Even if they declared independence, and didn't face military action, they'd only have the status of other unrecognized states like Somaliland or to some extent Taiwan.
