Declaration of independence by the vassals

[Rodak Polak 597]

In history, every time a vassal wanted to declare independence, he looked for a strong ally to defeat his senior.

That's why I propose that in order for a vassal to be able to declare independence, it must first conclude a defensive pact with someone to beat his senior. Only after signing defensive pact  (but not with senior) vassal unlock the option to declare independence (previously this option was unavailable)

I think it is easy to implement and makes more sense than declaring independence in a situation when you don't stand a chance against a senior on your own.

And if it is added, it would put : 'civilisation' war of independence.
