I propose that we all become pirates. Not pirates per se but we will attack ships on the sea. We could easily cripple the biggest countries by blocking their imports. Most ships travel through the same narrow routes which can easily be blocked. It only takes a small group of people to take over a ship since most crews of ships are unarmed. Small ships can't be detected by radar because they are too low; therefore, the ship is easy to sneak up on. I'm sure we could do something to stop world trade. Rather than take over all the ships which is near impossible, we can take over a few large ships and block the trade routes. Perhaps we can just capture a certain type of vessel(like oil large oil carrying vessels perhaps) and hold them. This will cause a lot of harm to countries like the U.S., perhaps crippling it. This requires a lot more thinking and planning, but if we can gather money and supplies for this(which isn't so much since all we need is some food and guns and small boats) it may be feasible. Of course recruiting people might be a problem. Perhaps we could pay mercenaries. The beauty of this is that the ships can't be attacked because it would destroy the cargo. The ships must be boarded and it's occupants seized. Luckily, preventing boardings can easily be done. If anything we can sink the ships, it accomplishes the same goal. We can even blow up the oil ships and damage nearby ships that might be nearby trying to stop us. I won't bother with any more details since this is very complex thing and i believe i have adequately explained the general idea of this. Maybe perhaps even within ten years we might have the resources and adequately planning to do this.
