There should be an option to declare martial law during wars, that makes you able to pass any law in an instant temporarily.
Title. I always feel so hands off during wars, and I'm not talking about microing units, but in the political and economical side.
Imagine that I'm a politically and economically liberal country, which suddenly gets declared on. I have professional army and little authority. I suddenly get declared war by russia/germany/france/britain/us/china... any of the great powers, and they have mass conscription.
During the time my interest groups are done discussing if it's a good idea to recruit more soldiers to defend my borders against a massively superior foe, I'm literally being annihilated in the front.
There should be an option to enact exceptional temporary measures during wars, and revert back when the war is over or face political consequences.
