In recent years the collective west's (EU + NATO) diplomacy has gone from dealing with one train-wreck after another. In Libya they thought getting rid of Gaddafi coupled with some bombing would magically turn the country into a stable democracy. In Syria, instead of trying to calm things down, they chose to pour gasoline on the fire by giving money and supplies to the rebels and trying to bomb the country. I guess they thought this would result into Syria turning into a stable democracy. Instead they got an ISIS nest.
In Ukraine, the EU diplomacy managed to turn a trade dispute into a full conflict with Russia by completely ignoring Russian interests and rabidly supporting the coup against Yanukovich. This resulted in a hostile Russia (which is reorienting towards China) and a Ukraine on the road to becoming a failed state. And so on.
Where does this incompetence and unwillingness to learn from previous mistakes (like Iraq) come from in our politicians? Naivety? Arrogance? Apathy? Ignorance and stupidity?
Or is at all a result of just a bit of bad luck?
