Race,
Essentially you are right in your comment about cheap assets taking out expensive assets.
The Lesson Learned from that incident has evoked some interesting results.
At my local shipping port where US Military vessels sometimes arrive to drop military cargo and take on similar cargo.....in a US Port known for its sport fishing.....we get to see Armed vigilant gunners manning .50 Cal Machine Guns watching us pass by as USCG Patrol Vessels standby.....24 Hours a day.
If you happen to violate the Buffer Zone....you get to have a friendly chat with the Coasties who remind you to shove off smartish and not to come back again or they will ruin your fishing trip.
You can imagine the measures taken in a hostile location when such vessels pull into Port.
