With a bit of brain power you would figure out that you need a navy before any of this would work. But hey not everyone is as smart.You can make up your laws if you can back it up with your military but these people that you want to tax are much scarier than countries or armies like NATO.
All these ships and their freight are owned by multinationals who would barbaque world leaders alive if they proposed to raise fuel tax by a fraction.
& you want them to pay us millions every time they pass by us?
That reminds me of something...
