Afghanistan, Iraq, and Libya were all completely different situations.
One was an instance in which the country was harboring people who attacked us, another was a war of choice, and the third was a humanitarian intervention.
They all have very little in common and should not be lumped together.
The commonality was a stable government which was toppled and led to the country falling into civil war and chaos.
How about instead of nitpicking you address the question though.
Libya was not stable at all considering half the country was in rebellion
