Two days ago I posted an article on just how rapid was the downfall of democracies in the last decade: https://news.ycombinator.com/item?id=27320565
There are less functioning democracies today than in 1991.
The truth of life is simple. There is no deep, philosophical argument to it. Who wins, rules, be it a democracy, or totalitarianism.
If you lose to totalitarians, you die. If totalitarians lose to you, they die.
Do not discount military action as sometimes the only option on the table to defend, and solidify a democracy.
