You don’t know which country, its random.
You cannot leave this island, you cannot end your life, you cannot abdicate your position.
Your country is immune from military attacks for 10 years, its literally impossible. There’s a magic force field protecting the entire island and the entire airspace up to 41,000 ft (max civillian flight level) and 12 nautical miles sorrounding the island. Enemy military are unable to enter.
You cannot get kidnapped or killed or like fall into a coma, or anything of the sort, you have plot armor for these 10 years. Any assassination attempts will magically fail.
Your population does not have plot armor they can die.
The enemy can send spies.
You get to choose the location of your island at the start. Things spawn in, and has a random amount of development of an average developing country, history, culture is randomly filled in and backdated. Everyone speaks your most fluent language and is literate.
You have zero nukes.
I’d make large bets with any rich entity that they can’t kill me. When they can’t, collect monies. Use that funding to influence all military powers to support and protect my island at the end of the 10 year protection. Use the rest of the cash to build renewable energy, sustainable food sources, universal healthcare and bunkers to protect the population. Would also offer assistance to citizens that want to flee before war.
I’d choose a location near the equator, both of focus on solar power, and for ideal rocket launches.
