each state in the US is its own country

They were one state, the two emperors were co emperors

yep, and the military will be weakend, because now you have 50 heads of states and 50 independent armies trying to coordinate a battle plan

it really doesnt work as well as you seem to think

Except it was 2, and the 2 armies were literally the reason the Empire survived

It didn;t weaken the empire, its the reason the empire survived

had the empire kept

one army

look at what happened in the 3rd century crisis, it would have just repeated itself

so yes arguably

if you consider them seperate entities they got weaker

but they werent

and thats what im trying to say

they did get weaker, hence the west fell quite soon after relatively speaking, the east survived, but that does that matter when half of the empire died so quickly compared to the other half

I think we're disagreeing over the wording

and not the actual facts

I'm saying it was a single entity, so it did not get weaker

you're considering them seperate entities

what i'm saying is

i am not actually, im considering the command structure as seperate.... as they were

Yes, but they were both technically

part of the same state

so they should be seen as one

It was still the Roman empire

same state, so what? they still had two independent armies

but with a different administrative heads

one being based in the east, so he can guard and govern the eastern provinces

and one in the west, to do the same

but both of them were heads of the Roman state

and saw themselves as being one entity

when the west was falling the east did not mobilize to help, but rather strengthened its own borders with the muslims

Uh what

one second

give me a second

Islam wasnt a thing till the 7th century

the Western Roman empire fell in the mid 5th

muslims, arabs, again, im using generic terms because im rusty with this shit

so I think your time line is skewed

and

the east actually tried to

im simply refering to the people in the ME
