I don't really know why some coasts are not protected, but my guess is that it's expensive most of the time to put up sea defenses... Some may be missing defense because it's not eco friendly (hard engineering, that is) and not very attractive. This lowers the value of beaches. Then there are some beaches on small islands or isolated coasts that maybe don't really need the protection because either no one cares or there's no need for them. Isolated Coastlines don't really need them...
Anyway, this was my geography homework question and i think I may have answered it... Maybe... Wtv.
Hope this answers your question!

It probably protects against tsunamis
The US Coast Guard only protects the United States, they do not go over seas to fight.
An advantage of a concrete tetrapod is that it protects coastlines from waves. A disadvantage is that when they are used, it is hard to find a beach to go to where you can see the coast.
The department that primarily protects us from terrorism is the Department of Homeland Security (DHS). Within the DHS, agencies such as the Federal Bureau of Investigation (FBI), the Transportation Security Administration (TSA), and the United States Coast Guard (USCG) work together to prevent and respond to terrorist threats.
