I wonder why he can't travel to Latin America. Is it just the issue of not being able to transit through Western Europe or U.S. airports and the lack of direct air connection? Why Mr. Assange does not arrange a private jet flight for him? Moscow to Caracas is under 10K km so it should not be a problem. Even if that's expensive (maybe $200-250K), a few months of living in Sheremetyevo will eat up as much money, or more.
