Hi, everyone.
It's very simple.
All options below (except for some exceptions) have gradation from 0 to 10

War diplomacy, ana and not only

We need to create some Options to analyse statuses of all empires :
1) Fighting Capability
2)The correlative Power of the fleets, AI's and opponent's
3)The correlative Efficience of the fleets, AI's  and opponent's

4)industrial capacity 

5)Infrastructure Development

6) Enemy's war policy 

7) Course of the War.

8) The need of smth(from dust to territories)

Explanation.
1) FC - "Do i have fleets or troops? Can i engage and defend myself?"
0 - i cant create even Settler and cant protect myself phisically.
10 - My fleets are strong and numerous enough and will be ready for battle at the click of your fingers


2) Correlative fleet's power(my and opponent(s)) - overall power of MY OWN fleets and VISIBLE(!) and Perspective(how many he can engage or create in short perspective (1-10 turns))(!) or Encountered(!) fleets. (Any of this parameters HAVE TO be evaluated) 


3) "How many times i won and what kind of fleets won/loss mostly?"
This parameter can also influence the ship-engineering AI to create counter.


4) Systems which can(right now) or could(if i more IC and fleets right now - reference to 1 and 2 parameters) create small ships in 1-2 turns(early game)/medium ships in 2-3 turns. 


5) In descending order of values: (overall)

Acceptance, Dust,Production for System and Empire Economy/Infrastructure , Science, Strat.Resources, Luxury, Influence, Food (Food must be prioritised in new or growing systems)


6) Enemy's and my own war policy . How defencive\agressive is he, what purpose of his actions (https://www.games2gether.com/endless-space-2/ideas/140-goal-driven-diplomacy), from which moment/my action he became aggr./def.?


7) Course of the war. 0 - total failure, surrender. 10 - I WILL CHOP YOUR HEAD OFF AND S*** DOWN IN YOUR NECK!))))

8) Need in smth - no need in introduction.
