It's not impossible, but it may not be fun. When a big country declines, you see that the data reported to you in each round will be false. Obviously, the tax revenue is sufficient, but the national treasury just has no money. Obviously, the people are happy, but they are uprising everywhere. You click the mouse to execute the command, and after two rounds, the system tells you that the execution failed. Once again, the system played hundreds of pop-ups in a row to ask you to cancel. Officials sent to fight corruption are more greedy than the following people. Worked hard to gather together an army of tens of thousands of people, only to find out the real fight.
