The governments of the world have come together and decided to attack the small island nation after many failed attempts at stealing their technology. defenses Bombing or invading the land is pretty much impossible they have metal storm guns set up everywhere on the island to stop nukes and other missiles or paratroopers. Railguns and predator drones are set up to deal with any hostile ships. Undersea mini-drones armed with torpedoes are set up to deal with any submarines or any undersea threats. Biological attacks are pointless the small island nation health care that is a cut above any other country. Treatment and cures for pretty much all diseases that could affect the country have been developed and revenge would come quickly and savagely to whichever country did it. Whether a fusion bomb going off in a random city in that country or drone strikes hitting governments all around the globe. Merely using an e.m.p on the island wouldn't work because all technology on the island is e.m.p shielded. Cyber attacks don't work the technology that the small island nation uses isn't compatible with anything a different country uses and if you could make your technology compatible with theirs have fun getting passed a true AI running on a quantum computer not to mention their computer system is air-gapped.
if it helps to sum it up I am asking can we siege the unsiegeable.
please ask for information if needed
Edit they are trying to steal the technology from the small island nation
