My suggestion for thinking like a Corleone would be for Trump to take a cue from the Christening, and take out the following people simultaneously:
Our friend in North Korea
Soros and Co
Our friends in Iran
The Mexican drug cartel
Our friend in Venezuela
This list is far from complete. But it would be good to do this all at once
Or something like the Settling of Accounts from the Children of Dune miniseries.
