And Jesus's last words on the cross as he hung over his Jewish People
"Wait till my little brother Hitler gets yas ya bastards!" 
What goes around, comes around.
From a Gay Messiah to a Redneck Prophet.
...which is why a Messiah will come from the ruins of France to counter-balance the Prophet Mohommed for the Moslems.
Billions of $$ spent on Mars: too big to make dramatic changes so far. Too costly to do.
NASA hasn't even proven that Humans can 'live' in the Namib Desert - self sufficiently like a Colony on Mars.
Would be a far cheaper experiment.
Instead - NASA is offering minimal results, while just keeping its business ticking over and Scientists with grants.
NASA really needs to discipline its projects and only fund those that guarrantee greater results. Venus is a lost cause too.
Not the best time to blow millions and billions of just letting Scientists/NASA play with latest techno toys. The results from Mars will be very minimal compared to other planetoids out there.
Like spending billions on trying to live in the Sahara, when there are better places to consider.
