I am just wondering if you know what the "Treaty of Brest-Litovsk" actually said. I get the Feeling you only look at the wiki map and think "WOW they took a large piece out of the Russian Empire".
I agree that the territorial losses of Germany (not including colonies) are not as vast as the territories that the Russian Empire lost. But the overwhelming part of those territories were not transferred to the Central powers, but were territories that wanted to break away from the Russian Empire (Ukraine, Finland, some Baltics). Thats comparable (by Quality and probably quantity) to the territory Austria Hungary lost)
Now to other (selected and comparable) issues.
Navy ships - Germany had to surrender (most and best) of theirs, Russia could Keep them
Army - Germany was limited in Army size, Russia had to demobilize
Germany was prohibited to use (modern) weapons - no such Limit on Russia
Russia lost a sizeable part of Industry and mines (most went to sucessor states, or probablle sucessor states like Poland) - Germany lost for example the Saar coal mines (not the territory but the mines were now French property)
War guilt - well no such thing in the treaty with Russia.
War cost - both sides took their cost in B-L without demands to the other side. Versailles Germany had to agree to take on teh war cost eof the Entente (later it was fixed to around 269 Billion Goldmark). In an addition (August 1918) to B-L Russia agreed to pay 6 Billion Goldmark... (but this Addition had additional Agreements, some of which benefitted Red Russia - The russians even considered to ask Germany to send soldiers to fight against the Entente Forces on Russian soil ! - that Highlights the severness of German demands - the loser actually considered to INVITE the former enemy to help out
Sure B-L was not a light peace (and the Russians later said they should have taken Germanys original terms, because B-L later was harsher - maybe because Ukraine had made peace with Germany and wanted support from Germany
), but it let Russias sovereignity of the remaining territory fully intact. Versailles grossly limited Germanys sovereignity.
Russia could negotiate the terms, GErmany was FORCED to take the terms.
B-L had under 20 articles, Versailles 440!
What about the patents and rights Germany lost at Versailles?
True Russia lost more percent of ist European territory.
BTW did you know that only the English and French VErsions of Versailles were "binding" - For B-L the Russian text stood equal to the German... if questions would arise.
