Exactly, nineteen50, you're one of very few who really 'get' what's going on here!
Brexit is merely a mangled and misunderstood, but highly prescient sign, of EMPEXIT (to Exit Empire) --- the fast swelling "Political Revolution against EMPIRE" which is NOW organically evolving from Bernie Sanders' incomplete, vague, and undefined "Political Revolution" (against what?), which very quickly will explode with the firing of a loud, public, world-wide, universally humane, but non-violent, "Shout heard round the world" by all 'citizens of OUR world', to ignite a real and post-historical revolutionary "Political Revolution against EMPIRE". ---- Which as you correctly say, the Empire is trying to scare the people to vote for Empress-in-waiting (and War Hawk) Killary, but now the Empire is scared!
All of humanity is gathering ourselves to overcome this "Crisis of Humanity"
brought on by this Disguised Global Capitalist Empire as is so clearly
diagnosed by Professor Robinson, Noam Chomsky, Michael Hudson,
Christopher Hedges, Morris Berman, Zygmunt Bauman, Michael Hardt,
Antonio Negri, Karl Polanyi, Chalmers Johnson, Howard Zinn, Hannah
Arendt, et al.
As Professor Robinson so clearly diagnoses and fingers Washington as the metropole of an America that has metastasized into the heart of this global Empire:
"The U.S. state is a key point of condensation for pressures from dominant groups around the world to resolve problems of global capitalism and to secure the legitimacy of the system overall. In this regard, “U.S.” imperialism refers to the use by transnational elites of the U.S. state apparatus to continue to attempt to expand, defend, and stabilize the global capitalist system. We are witness less to a “U.S.” imperialism per se than to a global capitalist imperialism. We face an EMPIRE OF GLOBAL CAPITAL, headquartered, for evident historical reasons, in Washington."
