Are they still mad at that spanish-American war deal?
No, they have gotten over that, for the most part.
They are still angry at us, however, because we supported Franco back in the 1950s in return for his support against the communists. The Spanish left has never forgiven us for that and now they see a historical chance to get even.
You have to understand that Spain was under Arab rule for 800 years, from 710 to 1492 IIRC. So for them, it's six of one and a half dozen of the other...at least that is the only conclusion I can draw from their cowardly reaction to the railroad bombings. The Spanish military must be seething, but the cowardly government holds the power.
Nah, the socialist pansies are still pissed that we made friends with Franco...You remember him, the Franco who kicked the socialists/communists/anarchists' collective asses during the Spanish Civil War (1936-39).
