Sorry if i'm late for this, but as an spain citizen i guess i can make my opinion:
It really seems pointless to go to war for just an small piece of land, yes, it has been owned for 300 years, but who'd really care about it?
I know the UK went to war for pieces of land such as the Falklands, but that was 1980.
Pretty much what i've heard seems likely to be a threat over Spain, but obviously things have cooled down.
Neither of the countries'd like war, i can assure that, it'll bring much more than Spain.
War over a little piece of land is something that could happen on the 20th Century (Such as Danzig) But think twice, it's 2017, people are civilized.
In my point, i don't want war, and a pact could be perfectly made for it, but if both of our countries want to bring it on, remorsements'll occur.
Overall, it's just really pointless, and if we go to war, i guess another years of disaster'll happen.
To all the people comparing Equipment, come on, really? There's no point except statistics.
Thanks for reading, no hate to the UK.
