> C. The renaissance dam is a gravity dam. Giant concrete structure. It's not going to be easy to destroy.
To put this into concrete terms: the Renaissance dam is 476ft tall. According to Wikipedia[0], non-nuclear bunker buster bombs are limited to a penetration depth of ~20ft of reinforced concrete, which would barely dent a dam this size. Even the USAF would have a hard time destroying this dam from the air.
