no sir, you are wrong, be sure that after the first military intervention, as you are suggesting and innocent blood someone will take care about this issue, because Spain today is part of EU and we all are citizens of EU and it is forbidden to send military force against people. If that should happen then Spain risks to be suspended from EU and there were already cases about that in the past with other EU members for really little issues, so this is not the way of handling this situation anymore.
I regret to have seen GC beating people just for preventing a vote and failing to prevent anyting, this was the wrong way. If the referendum was illegal as you are writing, should still happened but not be recognized and managed as never happened , but seems someone was scarry about the results of a referendum to try to prevent it.
