A picture is worth a thousand words

The way i see this as i know what kind of person is Lindsay Graham my friend done business with him long time Ago , so i can say that this person never forget betrayel zelensky told him to make deal, so now Lindsay Graham can take legal action and arrest warrant could be issued then they can Do all the investigation where is all the money.
In this world it's easy to take money because law enforcement agencies and Anti money laundering agencies working fast all over the world and evem russia will cooperate with USA if there is order from USA law enforcement as Putin is also with law enforcement background and he respect laws.
Btw, USA specially the Lindsay Graham want money definately they get it.
There is no way anyone to escape from usa justice system and If zelensky not cooperate Im sure Lindsay Graham will start legal actions Lindsay Graham flight to ukraine and spent his personal time and money to settle deal nobody don't invest their time or money regadless of money the TIME is also expensive.
Im not here to say who is right or wrong but Im just predicting the outcome of this situation here.
Based on my life experince and strong knowledge about law and justice system i see that lidsay Graham can take legal action against zelensky, untfortunately zelensky did not study the USA justice and laws and he did not hire the lawyer, because If you deal with usa you need to know the law international war law and usa justice department laws If you make even small mistake the ones who knows law can open legal case against you.
Zelensky is just small down guy who was try to play big guys game without learning the rules first.
Im sure Lindsay Graham got best laywers in this case.
Btw...the owner by USA justice system the Lindsay Graham could be the owner of ukraine minerals If us justice system approves that it was unauthorised move to give this to uk instead of the lindsay Graham.
