I wouldn't call it the "best scene" but it has stuck in my brain since the first time I watched it.
This is what war was/is. This is humanity in a nutshell.
In the House of Rothschild [1934] movie, Nathan Rothschild said "My father said never use money to start wars - only to end up."
How does one "spend money to end war"? By spending money to send soldiers to kill the soldiers of other armies.
Rothschild logic is amusing.
