He actually wants to attack Donnie Block and John Block.
It turns out, in Meyer Lansky's heart, he has made multiple considerations.
First, of course, he hopes to withdraw deposits from Breton Bank through these people, then force Donnie to submit and agree to join their smuggling business.
Second, if Donnie disagrees, they will resort to violent means.
So after Meyer Lansky discussed with those people, they came to the following conclusion.
Organize two groups of daredevils.
The first group of daredevils will go out to sea by boat and search for John Block's whereabouts.
Then take out John Block!
The second group of daredevils will disguise themselves as gamblers and head to Atlantic City to find an opportunity to take out Donnie Block!
The enormous profits brought by the smuggling business are enough to make Meyer Lansky and others take risks.
Moreover, they are inherently entities walking on the dark side of the world, preferring to use violent means to solve problems.
