Edit: I think the default setting for the period whenever there's not a specific war set leaves Spain and Britain at war anyway, as seems to be true for every period
. After all there's a (completely apocryphal and rather in poor taste) quote attributed to Blas de Lezo himself saying that "every good Spaniard's duty is to always piss facing England" (of course it's apocryphal because, as the good sailor he was, he should know you always piss facing leeward, and considerig the prevailing winds in the Bay of Biscay where he hailed from, facing England would end more often tan not with you showered in your own urine).
