The fall of the Berlin Wall should remind us that the walls of authoritarianism can be destroyed and democracy and freedom can be extended. The struggle of the Germans and Eastern Europeans shows that the fight against authoritarianism can be successful and brings democracy.
But we must be aware that new walls against freedom and democracy are currently being built and those autocrats all over the world are trying to introduce new limitations on freedoms. All democrats must fight against them.
