“Are there free elections in any declared theocracy, dictatorship or various one/two party systems where choice is either deliberately limited or non-existent?”
Certainly not in any of the above except for the two-party systems.
“historically the US never put a value on democracy itself but more on installing friendly governments”
Er, it’s complicated. Yes, the US installed friendly regimes in some countries. On the other hand, it crammed democracy down the throats of the Japanese after WWII, and ever since the Carter Administration has placed greater emphasis on supporting democracy. And certainly no other government in history has done anything to support democracy in other countries.
“ “We disagree with the guy so let’s foster internal conflict since anyway venezuelans will do the fighting and dying” isn’t much of a reason.”
Your verb ‘foster’ here is too vague to provide a basis for discussion. The internal conflict in Venezuela is driven by the oppression of the Maduro government and the economic collapse. The US does want to see the Maduro government replaced, but it is taking no untoward action to make that happen.
