Libya, Syria, Venezuela, Zimbabwe. Hmm what do all these nations have in common?

Mugabe served his nation with distinction and he did so for a long time. Mistakes were made but he is no criminal. Zimbabwe never attacked any nation, never dropped Atom bombs on other people, never genocided anybody. However one problem with revolutionaries is that when they get to power and usually on a wave of popular support or the power of the gun or both they refuse to leave. They glue their backsides to the chair of power and cannot be removed. Mugabe is like 80 or 90, well above pension age so it's time for him to step aside and let another Zimbabwean serve their country.
