How to Destroy a Country's Infrastructure 101.
 

What a methodology to completely destroy a country's government infrastructure so there is minimal political fallout for the US.

1. Decimate their armed forces.

2. Make sure all local police and law enforcement agencies aren't functioning for a week or two. (i.e. shut down the power grid and telecom capabilities)

3. The people will then do the whole job for you. Just sit back and let them loot, burn, and destroy it all and go into total anarchy before you decide to start and restore law and order.

Classic!

You forgot :
bomb them occasionally for a decade and have a commercial blockade on them.

And you forgot to mention that the country who "liberated" them is forced to bring liberated country's economy back up, while the liberator's falls to shit.
