You mention Nigeria. On any given day their system could collapse due to evil, warring leadership there, terrorists, and pirates. As a matter of fact, next week, my company is shipping two container loads of a small-craft barriers to Nigeria stop the “pirates” from approaching boats, docks, etc. It is definitely one nation we should not rely on.
WSJ had a report this morning on pirates over in Somalia. This pirate activity is growing and could have an impact on shipping and therefore world economy. Send in the Marines, sure, but that is not cheap. It’s all going to continue to get more expensive.
