arming cargo vessels to defend against pirates (this still annoys me)

This issue is really old but for years I can't get over the fact that cargo ships in dangerous waters do not have guns to protect themselves. Normally I can relate to both sides on an issue in politics (to some degree) and it wont bother me as much when things don't go the way I believe it should but I haven't seen a single reason that I find at all legitimate. Pirates target cargo ships because they are unarmed. I is undeniable that a presence of armed personal on cargo ships would correlate to a decrees in pirating incidents. I squirm every time I see diarrheal statements saying violence is not the solution to this problem. I can't even say that it's bullshit because bullshit is more solid and firm, this is weak spineless pacifist weak sauce. Arming ships isn't about killing pirates it the same way arming police officers with guns isn't about killing criminals. It's one thing to say that Somalia needs help to stop the cause of pirating but that still doesn't make arming ships bad. It's like saying the presence of law enforcement is bad because it doesn't fix the economic a social motives of crime. There are other reasons I heard like ports don't allow ships that are armed, or there are arms embargoes. I think the safety of the sailors and the multi-million dollar cargo clearly more important than any of that.

Here's an idea why don't they arrange a legitimate Somoli escort service, it'll a lot to make it work but it'll help Somalians make a decent living while giving ships the protection they deserve.

Another idea someone already thought of

I had this idea for a while about about robotics but I recently found out that it's already been thought of. here's what it is in a nut shell, people want to create robots and humanoids and to do that you need acutuators of some sort to act as the individual mussles, currently there are solenoids, stepper motors, experimental muscle wire stuff, pneumatics and hydraulics. but they all suck in their own way. Meanwhile systems that rely on combustion reactions, like gas engines provide large kinetic potential since it relies on the expansion of gases in a combustion reaction, the idea is to create an actuator that operates on an expanding fuel, the system would be much like a system of pneumatic cylinders that use an expanding fuel kinda like the cylinders in a gas engine only with a unique fuel possibly a monofuel that reacts with a catalyst in the cylinders.

well here's the paper that proposes what I thought was my idea I haven't read the whole thing because I'm not paying for a membership
