No ma'am, we're talking about every day conditions not how a dictatorship controls its people.
We didn't invade Argentina because Peron was throwing people from planes over the ocean. Killing people by dictatorial regimes is happening every day and we don't hear about it. Will this constitute instability in all these countries? Hardly.
I'm sorry, but this is a debate where we seem to have no mutually agreed upon starting point. When dictators are wiping out entire neighborhoods to quell the constant threat of insurrection, the situation is obviously not "stable."
