I don't know under what prism you do not consider the PP party not nationalists, when they are the direct successors of the Spanish National Catolicism movement that ruled Spain under Franco's dictatorship.
Do you know what? I was there, I saw the transition, I saw the people and I saw the evolution. What you say is not even wrong. It's just nonsense.
PP is a standard conservative party, equivalent to Puigdemont's CiU (now PDCAT) and that has been in the government with the support of CiU for years, during Aznar times.
PP turned a blind eye to catalonian nationalists' abuses when they needed them to keep power. Now they're starting to see the consequences.
Rajoy must be the laziest prime minister the world has seen. He wouldn't move a finger without absolute need for it. Even in this dramatic situtation he has hold his breath until he was risking stiff penal prosecution for himself had he not acted!!
Suggesting he is promoting the escalating is not only untrue, it's ridiculous.
