Mars is always sunny and, in any location we might colonize early, there's never any precipitation. Antarctica, not so much.
Antarctica gets far less precipitation than Arizona.
In 6 years they got that government thrown out and Yanukovych installed as President, a highly pro-Russian president.
Where "overthrown" means democratically elected in a fair election.
You also missed the point that Russia only intervened after the elected president was removed unconstitutionally.
