Under Franco Spain was civil, law abiding and NOT MARXIST OR MUSLIM! Franco's forces fought the Communists and supported Christianity, not the other way around as Hollywood would have you believe.
When the situation becomes dire enough, not just in Spain but in other parts of Europe, the door will open again for figures like Franco. The UK, France and the Netherlands are on the cusp of open, armed hostility between Muslims and non-Muslims. That is the big “holy war” the jihadist culture of the world longs for.
