Oh come on! That just is silly. These people aren't anything more than terrorists! You cannot shoot anything at a military vessel underway for any reason. These people get everything they have coming to them!
I have said it before, and will continue my mantra. Every life is sacred, but mine is #1. I would never endanger myself in a situation against a military force with clear SOP's regarding an attack. Shoot at a USCG vessel and see how many holes you have! The Japanese have done nothing wrong. These terrorists should be at legislative meetings, not on the sea. You cannot tell a foot soldier to step away from his orders, you need to go to the one giving the orders.
Be sensible. Things will never get better for the animals you want to protect until YOU act like a reasonable person. Shoot at me, your dead. Reason with me I will be reasonable with you. I know I speak for anyone who thinks logically. Fight the battle where you have a chance of winning! On the sea just makes you look like you are trying to make it to the news!
