Would it be a cool feature if you could fund rebels in a certain country? Like, you send a certain amount of money, say, $30,000 to help rebels in a country for an extended period of time. They decrease morale and start uprisings to switch to your country's nationality. But there's a catch. The closer a province is to its country's capital, the harder it is for rebels to overtake them. Also, you'd need to constantly give them money so it'd be costly for short term but worth for the long term.

I was using the 30000 dollars as an example and when I talk about a rebellion, I don't exactly mean in one specific province but instead over several provinces. I think the price should be flexible and players should be able to pay what they can. What I'm saying is that players could choose how much they want to fund the rebels in said country. The amount of money they spend affects how effective the rebels are. If someone paid 1 million dollars to support rebels, they'd be very effective compared to if someone paid 30000 dollars, but capitals are invincible to these types of attacks. I also think that it should be a feature for people with high command so this feature isn't being abused by everyone.
