I can see this argument 

 A lot to unpack there. 

You wanna get real technical I think it was what. Right after the titanic sank?

Its like OK our country has been in so many overlapping wars and regime changes. Where do we want to put the start line here lol! 

 Passports introduced at mass scale during the WW1 to prevent free movement of the people during war time. Their use supposed to be discontinued after war ends.

They're still in use, so technically we're still in WW1 

 Intriguing story that I am unaware of. 

I wonder what it would take to officially end it since all of the original parties do not exist in their original form?

If there is more to the story. Please tell. Fascinating.
