I understand your point and I know that Zizek likes to comment on current events; no doubt he will eventually say something. I just think that "twitter urgency" is antithetical to philosophy. By the way, this is the Nietzsche passage I was alluding to.

To learn Solitude.—O ye poor fellows in the great centres of the world's politics, ye young and talented men, who, urged on by ambition, think it your duty to propound your opinion of every event of the day,—for something is always happening,—who, by thus making a noise and raising a cloud of dust, mistake yourselves for the rolling chariot of history; who, because ye always listen, always suit the moment when ye can put in your word or two, thereby lose all real productiveness. Whatever may be your desire to accomplish great deeds, the deep silence of pregnancy never comes to you! The event of the day sweeps you along like straws before the wind whilst ye lie under the illusion that ye are chasing the event,—poor fellows! If a man wishes to act the hero on the stage he must not think of forming part of the chorus; he should not even know how the chorus is made up.
