Oh, and as for The Prince. The key there was the use of presence and persuasion, to garner power in the court and realm. The way of intrigue and manipulation. Now, when a nation has the ability to have a 'generator' that can spawn and control hurricanes with the flick of a switch means they have access to amazing energy sources. Sources that only exist in theoretical physics (and the odd sci-fi movie). Meaning that they are amazingly (and this cannot be over-emphasized) developed in comparison to the rest of the world. Particularly if we are talking about hurricane genesis and control. They would not need to crack open a copy of The Prince since they would never need to be subtle. They would just outright colonize the United States since their tech level would be above anything we could come up with against them. Oh, and it would be colonization in every meaning of the word.
But hey, maybe they have 'a variety of possibilities' that would make them rather focus hurricane-genesis engines on West Africa, to create weather systems that would turn into hurricanes in the Atlantic, and then focus hurricane-control devices that would steer the tempest into the Gulf of Mexico, and then slam it right up the gulf coast. Hey, that makes a lot of sense.
And although Swiss and Spanish infantry may be considered very formidable, nevertheless there is a defect in both, by reason of which a third order would not only be able to oppose them, but might be relied upon to overthrow them. For the Spaniards cannot resist cavalry, and the Switzers are afraid of infantry whenever they encounter them in close combat. Owing to this, as has been and may again be seen, the Spaniards are unable to resist French cavalry, and the Switzers are overthrown by infantry. And although a complete proof of this latter cannot be shown, nevertheless there was some evidence of it at the battle of Ravenna, when the Spanish infantry were confronted by German battalions, who follow the same tactics as the Swiss; when the Spaniards, by agility of body and with the aid of their shields, got in under the pikes of the Germans and stood out of danger, able to attack, while the Germans stood helpless, and, if the cavalry had not dashed up, all would have been over with them. It is possible, therefore, knowing the defects of both these infantries, to invent a new one, which will resist cavalry and not be afraid of infantry; this need not create a new order of arms, but a variation upon the old. And these are the kind of improvements which confer reputation and power upon a new prince.
